Clowns

Using Spellbook of Knowledge and Wonder Wand on your monsters to draw cards and set up graveyard is the primary strategy.

Your main boss monsters are Black Luster Soldier - Envoy of the Beginning, Silent Magician, Silent Magician LV8, Chaos Sorcerer, and Quintet Magician. Main target for Summoner Monk is Silent Magician LV4 if you have Level Up! in your hand, otherwise go with Performage Trick Clown and link/xyz. Some cards can brick hard (silent magician 8 im looking at you) but most of the time it works out.

 

Note I only have 1 Silent Magician in the deck despite it being one of the best cards. If you can afford it/are playing online, by all means play 3 copies. The cards in this deck are all the ones I currently have on me so this is the ratio I have it at. Feel free to experiment and let me know if you have any better ideas.
