Number Five A creature with a playable power/toughness that makes an innocuous looking piece of carboard when it Enters has been a staple of standard for the last few years
Weve synchronized each booster with Traditional Foils, Rares and/or Mythics, Borderless and Extended-Art cards, and two Foil-Etched cards
But Izzet does like artifacts, so the usual trio of Oblivion Stone, Nevinyrral's Disk, and Perilous Vault are all fine board-clearing options
It also serves as another form of removal that may circumvent any protections like Ward
It makes cards like Aetherflux Reservoir incredibly easy to activate multiple times, and quite literally doubles the value of any lifegain source you have
Then if there are three or more creature cards in your graveyard, transform this creature
