Voranax, Sovereign of Purity

Vigilance
At the beginning of your upkeep, choose up to two target creatures you control. For each of those creatures, put a +1/+1 counter on it and it gains vigilance until your next turn.

Phyrexian Authority — Whenever an opponent attacks you with one or more creatures, if they control more creatures than you, creatures you control gain indestructible until end of turn.
