Alpha Jerry

You gain a number of additional combat phases
for each opponent after the first. For each
combat phase creatures you control may only
attack a single opponent and a different
opponent each combat phase.
Creatures you control have vigilance.
At the beginning of your upkeep and when you
become the Alpha Jerry manifest the top card of
your library.
Exile a face-down permanent you control face
up: You may play that card this turn.
