This will probably be really good, rated 5/5. But that also depends on how good a deck centered around Corrupt cards could be. With a few good ones in the right class... This could be devastating.

Interesting and could give some creative deck builds. I'm not sold on it right now but could be fun to play around with.

Wow... This is a creative and nice follow-up to OG Yogg. This is more likely to swing the game in your own favor, but I really don't like the inclusion of Rod of Roasting. Nope.

Very good for chaining spells, follow up with Solar Eclipse and then a huge spell that could be cheap with Kael'thas Sunstrider. Potentially scary.

This is scary... It has so much potential in Druid, especially with Kael'thas Sunstrider in the mix. Will see play and make your opponent weep.

Interesting, I don't really see a place for it in current libram builds (wich cards would you cut?) but could be really strong in swarm decks. 

Another story completely in wild!

At first glance it's weak, almost feels like a nerf to Galakrond. But if you play priest and use to have at least 3-4 spells in hand... Throw this in and see what happens.

Great for slower Shaman decks! I think 4 mana is right on the border to be "easily" corrupted also, so I expect this to be used. I'll try it in spell shaman for sure.

Not bad actually, not on level with other DH cards but could be useful if we'll se a meta with a lot of tokens.

I will probably hate to encounter this. I forsee fringe play as disturbance tool in standard.

I guess it's good for decks with a higher curve, since this has to be corrupted to be playable. Right now it's very hard to evaluate the mechanic but this card seems a little clunky.

Weird card... But I guess there are moments this could come in handy. Easy to play around, just place your taunts wide and you're safe.

Interesting! This might not be meta-breaking but looks fun. So, is C'thun added to your hand after playing all 4 pieces?

Quote From SideItem

I really like this prompt! I've made a bunch of (10) cost spells in my various customs class drafts but I don't know which one to pick (or if my class assignment kludges make any sense).

Bonzo Gonzo is my favorite effect, although the fact that I couldn't add the "targets chosen randomly" is mildly annoying for me. Paladin feels like the closest fit, although maybe it could have been a Warrior/Paladin mix.

Cheat Sheet is an ode to my love of milling decks, with Druid and Rogue being the two classes who can best restock their deck and/or cheat out such a big card early.

Discombobulation is an attempted one-sided board clear, essentially a Reno the Relicologist combined with a targeted Volcano. Although now that I put it like that it might be too powerful for just (10)?  Maybe an Overload is appropriate?

Those are some nice ideas! Out of those, I prefer Bonzo Gonzo. Class and expansion works just fine. I like the flavor of Cheat Sheet but it's a bit polarising. Discombobulation maybe deals a little much damage and are you sure you spelt it right? That being said, all three are great cards!

Feedback time!

Thanks for the feedback on The Final Reckoning! You have made some valid points, including that it could be good as it stands. Summoning 3 is one way to go, it's probably OP but maybe within limits for a 10 Mana Legendary? Making it a Libram is tempting (and I would of course change the watermark to AoO), but I don't really like the idea of cheating out this particular card for half the mana. Regarding the wording I used Dark Pharaoh Tekahn as reference and I think it's best as it stands. Other references regarding power level is of course Eye of the Storm (only a common!) but also Lord Jaraxxus because the buffed Hero power.

Maybe I will be able to give some feedback on my own later, there are some nice ideas out there.

EDIT, BREAKING NEWS: With the release of Day at the Faire, I don't feel like this card needs any buff and will probably submit as it is.

First I got an idea that I realised was a total rip-off of a former winner, I even used the same art for the token so I discarded the idea. (Culling of Stratholme: Destroy all minions and summon a 8/8 Arthas with taunt).

Then I got a new idea for the same class, feedback appreciated! Maybe it's to underwhelming? I feel permanent effects should be from legendary cards, hence the rarity. Maybe "summon 3 with taunt" is more fair?

EDIT: Should I even change it to a Libram?

Very nice!

Valorous Virtue is really nice! I feel it's time to review my cardback collection again and not just use "random" on every deck. :)

Thanks for all the feedback guys. I really loved this artwork and the idea of ​​exploration of the unknown that image awaken in me(connected to card advantage). After allthe feedback, I made some tweaks and made this new version. What you think?

 

The chances are high that you'll get an endless loop of discovers, so don't go there. I think you should stick to the discover theme however because great flavor. Maybe something like discover 2 spells/a spell and a weapon/2 Shaman cards/a legendary card etc and adjust the cost accordingly. I've also learned that Classic watermark is a big no-no here. ;)
