bruh, note that "returned to the hand" will made a infinite loop for WB, fits in perfectly for WB based deck. you will never deck out with this card. if it's returned to hand you'll eventually deck out.
Works well with Wonder Balloon. Even faced an Asian player that had a Sword of Deep Seated with Wonder Balloons. (That was my inspiration after losing to a few of those...grr).
Ended up in a tie with him after 50 turns (the game forced it). It didn't help I had 2 yet now 3. Someone tried to use Overwhelm yet they already wasted their only two while I decked them out. One of them gotten my Dog, the other one gotten my Mirror Wall. It didn't help I already had two Pot of Benevolence.
