When you play the "Fusion" Magic card along with 2 or more Monster Cards, you
  may be able to Summon a powerful monster! But beware: not all monsters can be
  fused together. Here is a list of every valid Fusion Monster in the game, as
  well as a list of all component monsters needed to make them. Remember: other
  monsters not on this list are liable to suffer from "Attribute Repulsion"!
