Why and How Konami made Floowandereeze? Are they just compeltely retarded?

[Supermaori]

They all are recoverable, they all are searchable, they ignore maxxc and Ash Blossom, they all can move in my turn, kill my cards, make a board that ends the game.
Seriously, they all should be banned. I mean it. They should make Floowandereeze unplayable.
