Forum:Necessary text?

Just wondering why it's necessary to put down "Must first be Fusion Summoned" for Fusion Monsters. I mean, it's already a Semi-Nomi by game mechanic unless stated otherwise. You don't even see that on Synchro Monsters or Xyz Monsters, which come from the same Extra Deck. 24.83.215.20 (talk) 07:56, March 30, 2012 (UTC)
