I think I like Suspicious "San'layn" the best, but I'm not really sure what the name is in quotation marks, and it would probably confuse a lot of people.

I do think Master of Searemonies steps on Trench Surveyor a bit too much, with both being Mage cards from the same set with the same statline that both Dredge and conditionally draw a typed minion.

My first thought when I looked at the card was that you WOULD know how much damage you dealt because you would Dredge first and then deal damage, and I didn't think it was OP because of how your deck would have to be stacked for that to work well. But now that I know that you can't know your damage beforehand, it's even safer than I originally thought.

I like War Council and Fresh Digs the best. Fresh Digs can probably cost 3 mana.

Do not go with this.

It's a mess to understand and it doesn't have the soul of a Colossal minion.

I like Scrapmetal Avenger the best. It feels like a realistic interpretation of Endless Infusing and it can't go too out of control like Denathrius could.

I don't like Corpse Researcher because the Infuse effect is way too sidegrade-y to be believable.

The reason I didn't go with Suspicious Diver before is because it felt too weak. Suspicious Usher and Suspicious Alchemist always give you a card to use right away (even if doing so would reveal the card you chose), but you have to wait to draw the card you Dredge. And if your opponent guesses it correctly, they get to use the card first. Another person also appears to have submitted this design, so it'd be best to avoid it (unless that was you).

Sadistic Spellweaver is a perfectly believable card, but it's not eligible for the competition since it only has one mechanic (Naga Synergy).

Koma, the World Eater is probably one of my favorite cards so far.

This is a fine idea on paper, but there's a massive game-breaking oversight with it: It applies the Reborn as an enchantment, and so is the part where it says it's Reborn with enchantments.

Therefore every time it's Reborn, it would apply the Reborn again creating an infinite minion.

Hey! Glad you decided to join us here. Hope you have fun.

Bonehull seems cool, but it's weirdly anti-synergistic with the Dredge since you want the Treasures to stay in your deck so they can upgrade, intruding on your Dredges.

Suspicious Angler is probably a more on-brand interpretation of Suspicious Dredge cards, but it will still feel like it's stepping on their toes too much, so it's best to avoid it.

Anub'arak, Crypt Lord is super sticky and I can see it being slightly annoying to play against, but it's probably your best bet.

If you actually posted that Illidan Stormrage as your entry, that would be the funniest troll ever. We'd still disqualify you for doing so, but it'd still be funny. I've give it a laugh.

Rexxar is cool. Hunter can sometimes spell-spam pretty well, but the effect can't do too much since after 3 spells, it stops doing anything, so he doesn't ever go too overboard.

Jaina is quite good thematically, but it does seem too much compared to Deep Freeze. Instead of simply one Freeze, you get a 3/9 that casts Blizzard instead.

I agree that Gul'Dan is better than Valeera. Valeera is quite awkward to use given that she's a 6-mana Combo card that requires you to have a sizeable board of certain minions that also happen to be good Shadowstep targets.

Gul'Dan doesn't have that problem. You just plop him and you're good to go.

I think this is a cool play into Kalimos and Bru'kan's Elemental powers, but I think in general this is probably too powerful. It's a 5/5 with no condition and all of the effects are incredibly solid. Stonemother's Blessing also happens to have a Common rarity gem, so remember to fix that.

Windlord's Blessing is also significantly weaker than all of the others, so you should try to either buff that one or lower the power level of the others to try to match it better.

I like Uther. He's quite simple, but his effect works pretty well.

Anduin is quite scary. Especially if you copy him somehow since they would both give each other Immune and make it almost impossible to get rid of him.

Even though I do think the first version is more exciting, I will agree that it's not particularly Mage-y. This third version is quite good. I will echo that maybe it can even be 4 mana. Mage is not really that good at minion spamming, and even Warlock which is good at minion spamming couldn't break Disciplinarian Gandling.

Your first Jaina is… quite a bit! It fully Freezes the enemy board and if they can't do anything about the several Water Elementals you made, you'll Freeze their board again next turn with the Water Elementals. Or just go face. Both outcomes are quite strong.

I don't like your second one as much because it lacks identity. It summons Frost Elementals, wants you to use Arcane spells, and gives itself Spell Damage for each (which it can't use that effectively in most situations since it's a 9 mana minion and it needs to be played for it to get the Spell Damage).

I agree entirely with Wailor. Use the second version's effect and the first version's cost and statline and you'll have the best version.

I like Warlord Garrosh's synergy with handbuffing. Feels like something he himself would probably do, and it makes a lot of sense flavorwise.

Gul'Dan has a great idea, but his effect is quite bad unless Warlock has specifically a Hand of Gul'dan in rotation since the Taunt Demons can be dealt with fairly easily in some situations and if they do, then you've just lost your entire hand. I think it's also a bit weird that his card name is just Gul'Dan. I think you should give him an additional title in there somewhere.

The flavor of Stern Librarian having Taunt was supposed to be representative of the fact that he knows you have overdue books to bring back and he's not happy about it, and eventually you'll have to confront with the less-than-happy librarian about it. I guess that aspect of the flavor isn't communicated well enough.

Regarding Demonsoul Scavenger, I do also think what Link said about the second iteration applies. It seems that it will just simply two cards which will be both in end up in the right-most spots of your hand. The first version does the job better.

As for what you said about Illidari Ambusher, how weird it is read "shuffle your hand" is actually the reason I didn't go with this idea myself. It some ways, it seems unclear, but it also feels like improper wording to me, although we have no precedent so we can't really be sure.

Something about dual-class cards in an RoS mini-set kinda irks me, but I suppose if we're imagining that these mini-sets would all be added at the same time in present day Hearthstone like the mini-set comp we just did, then this is perfectly fine. I might just have to learn to overlook that.

It feels a bit strange mechanically for Warrior since they aren't really that good at minion spamming most of the time, and Warlock doesn't really have the Bomb support cards that Warrior does, but it's an okay card overall.

Very weirdly and awkwardly, my list of cards from best to worse is a complete reverse of Wailors. Waterfall Visions is my favorite because it makes the most sense and has the most potential. I quite like it.

Pluxva the Soulbound is a cool little swap on Soul Fragments although it is quite limited by the fact that you'd have to draw those Fragments while you control it, which then encourages you to run a lot of cards that draw the Fragments to use its effect, but in turn that also means you're up all your Fragments that you could otherwise use for cards that destroy them (or Soulciologist Malicia which already has some anti-synergy with the other Soul Fragment cards).

Curious Experimenter is a bit unclear as to what "shuffling its stats" entails. Does that just that the sum of "A + B = C" will result in an entirely different (and presumably randomly chosen) A and B as long as it equals the same C?

Shallow Waters is my least favorite because it doesn't feel like a card for any particular purpose. For all intents and purposes, it basically just acts as a 0 mana Dredge in most game states. It also doesn't feel either Mage or Shaman at all, so it being a dual-class of both is particularly weird.

It feels a bit much in either regard. It's a 3 mana 4/4 Neutral minion that's basically a Madam Goya on crack. It can be used for the same "swap something small for something big" in your own deck or vice-versa on your opponent's board. Replace their big threat with a tiny, insignificant minion. All on a Neutral minion with excellent stats for the cost.

This also assumes that it doesn't have a chance to just repull the same minion that you just put into your deck. Can it do that? If it can, then that doesn't feel fun knowing that the effect always has a chance to just randomly whiff.

Xevozz is cool in theory and might slip an opponent up, but as mentioned, the fact that it's quite easy to remove does hinder its playability, and your opponent could even possibly take advantage of it by spamming a bunch of small cards that your deck can't use too well.

Reckless Seeker is one of my favorite cards of the competition posted so far. Makes a great use of the Spellburst keyword and there's some pretty fun applications with it as well.
