arena only obvi, its way worse than the coin elemental card which works on a similar philo of slightly better stats for a huge drawback. The Reborn is actually a disadvantage here. Makes cards that some 3 drops (like that vulture card for warlock) seem a lot worse.
Maybe it is a bit too generous! Silence Priest won't run this, which means no other deck will. It is an ongoing aura and there is Reborn too, (meaning its going to stick around) if it was just he first card is discounted then maybe.
As it stands this is just a nerf to the 3-mana evolve pool.
This card is actually not bad when you're being aggressive. It's never been bad when I've played it. Certainly i've never lost a game from it, but I have never actually put it in my deck. I just get it from Pharaoh Cat.
