You can reveal 1 Spellcaster monster with 1850 ATK in your hand, with a name different from the monsters you control; immediately after this effect resolves, Normal Summon/Set that monster. You can only use this effect of "Fairy Tail" once per turn. Each turn, the first time you would take battle or effect damage while you control a Spellcaster monster with 1850 original ATK, you do not.
