[@The Grey Dust]

Any Card that has potent removal with no real drawbacks is broken. (cough reason for Lord field bomb rank 4 to be banned) 

As is a Card that has one of the best removal methods in the game (force tribute doesn't count as destroying so your opponent can't activate a card in response to the force tribute as if their card was destroyed) Which then switchs control back to its owner... 

Its like a broken lava golem
