Auxiliary, Reformed

Whenever Auxiliary, Reformed attacks, look at defending player’s hand. You may put a creature card from it onto the battlefield under your control tapped and attacking that player
or a planeswalker they control. Return that creature to its owner’s hand at the beginning
of the next end step.
