How does this work with Clutchmother Zavas? Does it summon it at the vanilla 2/2, at ANY of the statlines it has been at or the statline it is currently at? And does it count each of them as a separate minion in the 'pool' of discarded minions?
This might be just what warlock needed. Finally a high value minion. At 6 it might be too slow, but depending on what you discarded earlier, this might lead to insane value plays. Naturally, it might be more a fit for mid-range warlock with soulfire and doomguard than a full-blown discard lock tho. Depends on how successful you can manipulate what you discard. Has potential to be a better Faceless Summoner.
