Big Bad Voodoo Card Review
I’m not quite sure why would you want to play that. It’s a single Evolve that’s delayed, because it’s strapped onto a Deathrattle. For 2 mana. If you have a minion you want to Evolve, you can just play Unstable Evolution once and it will be the same, but immediately. Minions you want to Evolve aren’t generally very useful on the board anyway, so you usually want it to happen right away, not to mention the fact that Deathrattle can get Silenced.
On the other hand, if you have a big minion you want to keep on the board, just play Ancestral Spirit. Minions you want to revive like that are generally better than random minions that cost 1 more. E.g. you won’t likely upgrade an Earth Elemental by turning it into a random 6-drop.
So, if you want to Evolve stuff, you just play Unstable Evolution, and if you want to keep big minions on the board, you just play Ancestral Spirit. This doesn’t make much sense to me.
