Xenagos, God of Revels

Legendary Enchantment Creature — God {3}{R}{G} 6/5

Indestructible As long as your devotion to red and green is less than seven, Xenagos isn't a creature. At the beginning of combat on your turn, another target creature you control gains haste and gets +X/+X until end of turn, where X is that creature's power.
