Wild has much bigger and better combos to worry about lol

 Solid for Duels though.

Can this card counter Polymorph/Hex

Going by the text, yes. Trying to transmorph it into a sheep would just result in you getting an additional minion.

There are many mediocre 5 drops in the pool, but a turn 10 4 mana 3/6 with 5 random 5 drops isn't a bad turn. However, there a far more powerful combos ingame so I simply don't see this having any serious meta impact. What kind of game are we playing where 10 mana summon a 3/6 and 5 random 5 drops is an ok-ish turn...Something is seriously wrong with the overpowered cards/combos ingame. Quests can die in a fire aswell.

Unstable Evolution.  Well there goes Wild.

Just the revealed location seems good enough to be run in current Midrange Shaman, so this will probably see play. It's also a pain in the ass to remove on turn 4 for a lot of decks.

Which is why I also must mention that this card will probably be despised similar to other highroll low-cost legendaries.
