[card]Phase Stalker[/card]

If Acherus and School can replace the word Scheme, then the names of cards are not necessary to solve this. Everything changed except the group of letters "CH" and its position in the word (always the 2. and 3. letter.).

In the Xaril-Xanesh-Xavius example, the letter "a" which is second in each word is literally just a coincidence. The …

May I ask, could [card]Dr. Boom's Scheme[/card] be replaced by [card]Acherus Veteran[/card]?

I got the same order before, using sets of two letters and finding them in each cards name.

[spoiler]GH-AZ SC-PT-AU-CH-RH
LauGHing Sister, *I don't know*, DiSCiple of C'thun, Ravenous PTerrordax, Bladed GAUntlet, Dr. Boom's SCHeme, Tundra RHino
Second one has to be [card]Flame Elemental[/card] cause it's the only one …

Does the order in which you showed the cards matter?

Jaraxxus it is!

Alright, a simple one. You're only looking for one card this time:

To live, or not to live, that is the question:
Whether 'tis nobler in locked war to suffer
The pings and damage of outrageous power,
Or to take Fury against a Field of trifles,
And by inferno end them...

1. [card]Cloud Prince[/card]
2. [card]Leeroy Jenkins[/card]
3. [card]Explosive Runes[/card]

So the solution would be [card]Fireball[/card]!

Fedrion has it 99% right, so I'm counting that as correct.

It's [card]Cogmaster's Wrench[/card]! anchorm4n got Hobart and Fedrion got Zapp, but the first one was the [card]Cogmaster[/card] himself (played in Mech Mage). What connects them is that they all have Cogmaster's Wrench in the art (well, [card]Cogmaster[/card] technically doesn't, but he's literally in the weapon's name).

No.

The riddle is probably too vague, my bad. It's been a while since my last one. Some big tips coming up to make things clearer:

[spoiler]The first card was a part of a powerful meta deck in the distant past. I'd say it's still an OK card (but I'm no pro), just really unsupported.

The second …

Nope.

Hint: All the cards have a certain mechanic/engineer theme.

Surprisingly fitting, but no. None of the cards are in Standard btw (third one isn't in Wild either...)

Nope

Nope.

Maybe it's too early for hints, but I want to make this clear: Each of the 3 paragraphs refers to a different card. All three have something in common - the card that is the final solution. Also the first line doesn't matter much, it's just for flavor.

Three hermits know me

One used me and found success
But now he's valued much less

One tried to improve all of us
But it was too small of a plus

One uses me now in battle
Usually to prevent nasty rattle

[card]Infectious Sporeling[/card]?

Wombo combo alert:

[card]Brann Bronzebeard[/card] + [card]Mojomaster Zihi[/card] + [card]Revenant Rascal[/card] x2 (with [card]Drakkari Enchanter[/card] + [card]Emperor Thaurissan[/card] setup)
Each player now has 2 Mana and you have a 5/5, two 3/3 and a 2/4.

How will Lord Barov work? You can't Discover, so will you drag from the HP to a hero icon? Or will you choose from up to 8(!) heroes?

Pogo Brann is the best build, change my mind.

[card]Fire Elemental[/card]? I think the specific number is 6 cause the number of the Beast is 666. Fire Elemental costs 6 and has 6 Attack, also its name fits perfectly with the first line's hint.
