Monstruous Satyr

Whenever an opponent activates a loyalty ability of a planeswalker, add {g} or {b} equal to the number of counters on that permanent. You don't lose that
mana. Put a +1/+1 counter on Monstruous Satyr.

Whenever a nontoken creature deals damage to a planeswalker, destroy that planeswalker.

Vile if you dismiss it. Fascinating if you befriend it.
