Sin will top at locals because well anything works at locals because it just needs to work well 5 times, rather than 12 in YCS, Jumps, Regionals.

Also I'd focus more on Sin Cyberend and Sin Stardust, and the deck posted just now looks really really really slow and inconstant with the only thing making it viable are the Duality, Trade-In and Malefic World.

Aside from that I'd avoid this deck unless you have the money to make it and you just want to play it for fun.

PS: If Paradox had to play a match he'd have a side deck to try to beat everyone but everyone knows it's impossible to beat Yugi and Yusei.
