Huh, good idea actually. Turn 5/6 pocket galaxy could bring back big mage. Nice catch.

Agreed, the mana cost is def. a mistake. I could see a card like this being played at at most 6 mana. After that its just too gimmicky.

We have seen steal mechanic before for minions. This shouldnt trigger deathrattle and you shouldnt destroy and equip. You should get it with however much attack and durability the weapon had when you stole it.
