If they want to keep the flavor text accurate, the obvious move is to make this cost 10.

Came here to write the same, but you have been faster XD

Should cost 2

very scary with shaman's unstable evolution

I didn't think about this until I got this combo through some evolution luck in a dungeon run

turn 4:  2x Radiant Elemental.

turn 5:  Red mana wyrm

turn 6:  Play Shadow Visions, discover Shadow Visions, play it, discover it, play it, discover it, (etc.) attack face.

Turn 6: Get banned

Using this card in my secret mage, works pretty good... if you manage to control this card a have a bunch of spells, you usually win

When you have Gadgetzan Auctioneer and this on the board and you explore Un'Goro XD epic value

REALLY dangerous with Lyra the Sunshard..

Edit: also be careful of Radiant Elemental + Shadow Visions shenanigans..you might end up dead on turn 6 after infinite Shadow Visions..just remove this damn wyrm immediately especially if facing priest or rogue.. 

This card is BUSTED. I laugh at people which don't realize it's potential. Vs priest you can even control the attack value, for example cast one spell to make it 4/6. They just can't deal with it without board, even dragonfire potion won't kill it and next turn they just die, Or take like 12 - 20 dmg.

This is my second game in casual while testing this utterly underestimated card:

This probably wouldn't break anything at four mana.

As-is it seems kind of meh, though maybe Rouges could stealth it and do something.

I've yet to run into that, though.

red wunz go fasta

Yeah. Thanks.

So what do you do to defend against a Rogue that stealths and in one turn buffs to 28 damage? Isn't that basically another raging worgen card that they nerfed because it was to powerful?

If you let it get to that situation, you'd have been equally fucked if it was an Edwin VanCleef or a Questing Adventurer or even just two free Arcane Giants who were stealthed instead. Making an exaggerated situation in which this card is OP doesn't mean this card is OP. It's actually a little too expensive imo.

When Blizard ran out of ideas, massive arcane missile(very unplayable i think)

The flavor text just basically wins the Internet for today. Oh, besides probably half the other flavor texts. Seriously, for what it's worth, Blizzard hit those out of the park Kappa

Not anymore. Mana Wyrm costs 2

Cabal Shadow Priest against a naked red mana worm

Ultra feels good man
