Asked in Yu-Gi-Oh
In Yu-Gi-Oh is Aqua Spirit a special summon from the graveyard by removing a water monster?
No, Aqua Spirit can only be special summoned from hand that way. The only time a monster can summon itself from a different zone, is if it specifically says it can. Plaguespreader Zombie is one - it states that it summons itself from the graveyard.
But without such text, then they can only summon themselves from hand.
