During the Main Phase (Quick Effect): You can Tribute this card and discard 1 Spell; Special Summon 1 "Witchcrafter" monster from your Deck, except "Witchcrafter Genni". You can banish this card and 1 "Witchcrafter" Spell from your GY; this effect becomes that Spell's effect when that card is activated. You can only use each effect of "Witchcrafter Genni" once per turn.
If you are f2p and you have not gathered at least 9999 gems ready to be spent on this box, i really recomend you to keep your gems for the next mini box. 60 packs will most likely spent for nothing since in order to make a witchcraft deck you will need at least 2 box resets. You will most likely end up with 0 gems and a not even half completed deck if you are unlucky. Spend wisely, think twice.
