Shinra, the Eternal Storm

Vigilance, first strike, haste
Prowess (Whenever you cast a noncreature spell,
this creature gets +1/+1 until the end of turn.)
Whenever another creature you control attacks,
exile the top card of your library.
Whenever Shinra attacks, you may cast any
number cards from exile until your next upkeep.
You may cast cards from exile as though they
had flash, and spend mana as if it were any color
to cast them.
