Mowu, Fierce Protector

Companion — Your starting deck contains a
Yanggu Planeswalker. (If this card is your chosen
companion, you may put it into your hand from outside the game for {3} any time you could cast a sorcery.)
Whenever a planeswalker you control would be
dealt damage, you may instead remove a +1/+1
counter from Mowu, Fierce Protector.
Whenever one or more loyalty counters are put
on a planeswalker you control, put a +1/+1
counter on Mowu, Fierce Protector.
