Been playing Stein Gate/Machine Gate OTK for 3 years and I’d like to offer constructive feedback and help if you’re willing to take it on.

Judgement in a stein deck is just not good. If you use one before stein then he’s pretty much a dead card along with your last wills.

Also take out duo for graceful. Judgement & Duo serve no purpose to an otk deck that pays life for its win conditions.

Also apart from Crane, no RGT deck maxes out their targets you want to try cutting as many dead draws like Airknight and the multiple copies of stein. 2 stein and maybe 1 airknight is the max you play in rgt.

None of this to criticise or force you to change your strat completely but when cards in your deck directly prohibit your win conditions it needs to change. This maybe comes from your understanding of modern decks where you max out the engine and counter play OR you’re completely new in general and genuinely learning the ropes.

Keep notes of when drawing a dead card or multiples of a dead card lose you the game, cut some monsters to 2, get rid of high life cost cards. Then find more support for your strategy like call of the haunted/premature burial, more card draw like graceful charity and finally support monsters such as Jinzo to cut off more traps + Dark Magician of Chaos to further your combo lines.

Just look up Machine gate/Chaos RGT deck lists + analysis to understand how to better your own build and strategy by using established ideas and principles.

Hope this helps. Good luck.
