Githzerai Monk 4W
Creature - Gith Monk (Uncommon)
Flying Psychic Defense — When Githzerai Monk enters the battlefield, tap all creatures you don't control. The Githzerai dwell in the heart of Limbo, intent on shaping the chaos of that plane with their powerful psionic abilities.
Some really strong options for white here, between turning an opponent's creature into increasing useless farm animals, or suddenly tapping entire boards worth of creatures.
