Vaika, Protector Seraph

Defender, flying

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.
