You can reveal 1 Spellcaster monster in your hand with 1850 ATK and a different name than the monsters you control; immediately after this effect resolves, Normal Summon/Set it. You can only use this effect of "Fairy Tale Tails" once per turn. The first time each turn you would take battle or effect damage while you control a Spellcaster monster(s) with 1850 original ATK, you take no damage.
