Proud Alkmenos, who would not bow to Erebos in death, is now bowed by his own hubris for all eternity.

Xenagos, God of Revels

Legendary Enchantment Creature - God

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.
