Kestri, Canine King

When Kestri enters you get twice X experience counters.

Whenever you cast a canine spell, create a treat token, its a artifact with "sacrifice this artifact: target canine gains indestructible until end of turn".

All canines you control have +X/+X, where X
is the number of experience counters you have. They also gain vigilance, haste, and trample (canines are foxes, dogs, jackals, and wolves).
