Animar, Scourge of Realms

Hexproof from monocolored.
Whenever you cast a colorless eldrazi spell place
X eradication counters on Animar, Scourge of
Realms where X is its converted mana cost.
Colorless non-token eldrazi creatures you control
gain annihilator X, where X is one tenth the
eradication counters on Animar, Scourge of
Realms rounded down. (Use only the highest
annihilator value, they don't add)
