Spark Corruptor

The starting loyalty of planeswalkers becomes 1.
Whenever a player activates a planeswalker ability
if that ability would add one or more a loyalty counter, Spark Corruptor deals damage to that planeswalker owner equal to its strength plus the planeswalker ability cost.
"Few people, harnessing such power, it's unfair for the
rest of us, and because of that, they should be
punished" -Rojas, the Corruptor
