Odysseus' Memorial Moon

Whenever a Wizard, Magus, or Spellshaper
enters the battlefield you may pay {1}{w/u} or discard
a card, if you do all other creatures that share a
type with that creature gain Prowess and Flying
until end of turn.
Whenever a Wizard you control dies you may pay {w/b}{u/b}, if you do create a 3/2 Blue Zombie Wizard creature token with Prowess.
