Attacks » Moon's Invite
When using Darkrai & Cresselia LEGEND's "Moon's Invite" attack, can you move damage counters to/from more than one Pokemon?
Yes. Basically the attack let's you rearrange your opponent's damage counters any way you want, as long as other effects, Poke-POWERs, Poke-BODYs, etc. will allow.
