This is the very frustrating kind of RNG that will often decide games, but I imagine it will be pretty good. Great synergy with warpath, blood razor, and this becomes very scary with Scourgelord up. Also, it puts your opponent in a really awkward position because trading into it will get ugly in a hurry but leaving it up can be disastrous.
Oh, I get it. This into shadow madness, divine spirit, divine spirit, inner fire.
Either way seems like warrior gets no great legends this expansion either it seems. A 3/8 that can't attack even with its effect should probably be 5 or 6 mana. At best it's 24 random damage spread over multiple turns.
