Forum:Magical Hats + Ultimate Offering

Okay. During your opponent's Battle Phase you activate Magical Hats. Can you then use the effect of Ultimate Offering to Tribute the Spell/Trap Cards that are now monsters to Tribute Summon a monster? Also, could you use them with Super Polymerization (And do they need to be face-up when you do so?)? Sabre Knight (talk • contribs) 19:39, January 20, 2012 (UTC)
