Tortolla needs a nerf?

Today I had it with Tortolla, after taking it to 3 hp, and next turn the opponent cubes it. I don’t feel stupid because I couldn’t take it down in one turn, and there aren’t many situations where you can. It’s already quite OP with the 30 hp and extra armor for control, especially when you can summon on it turn 5. So is it fair?

Or just put a restriction on cube that it can’t be used on minions that cost above 6, to prevent players from getting more value than what they invested.

High-level play is all about “getting more value than what you invested”.
