If you control a "Witchcrafter" monster: Target 1 Spell in either GY; add 1 card with the same name from your Deck to your hand. During either player's turn, except the turn this card was sent to the GY: You can banish this card and any number of Spells from your GY; Special Summon 1 "Witchcrafter" monster from your Deck whose Level equals the number of Spells banished to activate this effect. You can only use each effect of "Witchcrafter Masterpiece" once per turn.
Works quite well with 3 copies of Cosmic Cyclone:
One CC is usually in your start hand
This lets you search a 2nd one if you need it
And you can banish the CC from your GY to Special Summon Genni which can special summon Madame Verre
And if you don't draw a CC there's still a chance that your opponent uses one within his first few turns
