Forum:Fusion substitute monster argument

today at the local tournaments i ran a fusion heavy deck using king of the swamp's and earth hex sealed fusions.

these cards may act as a fusion material substitute if other materials are correct.

from the complaint of 1 player many began to agree with him and stated the monster must be on the field to be a substitute.

i know for a fact thats wrong and it can act in hand field and grave as a sub.

id like better clarification on this subject to fully explain how fusion material subs function.
