1 "Fairy Tail" monster + 1 Spellcaster monster
All "Prince of Fairies" on the field become Spellcaster monsters. During your Main Phase: You can Special Summon 1 "Fairy Tail" monster from your Deck or banishment. You can only use this effect of "Weaver of Fairy Tails" once per turn. If you Normal or Special Summon a non-EARTH "Fairy Tail" monster, while this card is in your Monster Zone (except during the Damage Step): You can target 1 Effect Monster your opponent controls; negate its effects, also its name becomes "Prince of Fairies".
