Vaika, Protector Seraph

Defender, flying, lifelink, vigilance
When Vaika enters play, return target permanent
to its owner's hand. Put X justice counters on
Vaika, where X is that permanent's mana value.
Other creatures you control with defender get
+0/+1 for each justice counter on Vaika.
Remove a justice counter from it: Vaika gets
+1/+0 and loses defender until end of turn.
