The card reads, "Instead of revealing an order during the operations phase, you may discard this card to resolve an Advance Order in any system containing at least 2 of your units."
Is this card basically an advance order? Like can a player have all their tokens in other systems but play this card and basically use an advanced order in a system where they had no tokens? Or is this basically allows the player to resolve an advance order that may be on the bottom of the stack instead of being attacked first?
