Thanks for the suggestions, I'll do everything you say, it's bad I don't have most of the cards you mentioned (I've been trying to geral mirror Wallace and kuriboh for an eternity now)
I don't know what your skill is (I can't read that) but since you use Yami then I assume it's Power of Dark? Remove those winged beasts, Pixie Knight, and maybe that worm(i forgot the name). And since you already have Blue-Eyes, Cosmo Queen is useless so remove it. Also remove Dark Effigy too, then add Sphere Kuriboh when you finally get it. Keep your monsters around 10-12 cards
