However, Vorel is actually quite different from proliferate. For one thing, he targets a specific artifact, creature, or land. Also unlike proliferate, he can’t affect players, which is a bit of a bummer. However, in exchange for these drawbacks, you don’t have to pick just one type of counter to double. Rather, Vorel will double every type of counter. +1/+1 counters? Doubled. -1/-1 counters? Doubled. Loyalty? Yep, that works (but only if you can turn your planeswalker into a creature). Even things like petrification counters and filibuster counters are fair game, as long as the target is an artifact, creature, or land.
