im confused on which to use because they both do very well

I say go with OTK- Stein if you plan on siding in burn like the Euro + UK players did. gl.

well- a lot of people entered with cyber stein there. only 1 top 8ed. its a luck game. depends on how lucky you think you are man.

depending on what you plan on playing against (which shonen is this?) deck devestation might be a nice techy maindeck. if you play against tomato control- you will have a hardcore advantage.

i actually met someone at Shonen Atlanta with a fun deck dev build. it was toolbox warriors. 3 reapers, 2 dons, 1 mystic LV2, 2 giant orc, 2 zombyra, chaos, sakuretsus, deck dev, smashing grounds.

basically- it went...
i'll 0-1 you
you can 0-1 me
lets get into a topdeck war
you are running a bunch of situational cards, and i'm not. haha- i win the topdeck war.

or- it went...
deck dev on turn 1
you have no hand
i'll just win



it was fairly ridiculous. toolbox is underrated and fairly stable in this current environment.
BUT- people are starting to tech in goldds... so it's risky too. you can get lucksacked.

its Arlington and the deck is kind of like this i'm still working on it.
