I can already imagine Mirage facing off against a villain.

"Oh geez! You have a gun/sword/have fire powers. Wait hold on!"

*summons a bunny rabbit*

"No.."

*pulls a card out*

"Heh is this your card? No...all right.."

*Poofs in interlocking rings*

"Heh pretty..."

And so on. Gonna be a real slap to the face to get all these "heroes" into the field.
