Basically a pure mitsurugi deck with a fiendsmith engine to help it play better under interruption and droll, instead of ash you could play mulcharmy purulia but i don't own any due to budget reasons. Side deck can be changed on whatever you like to do, i like to swap full boardbraker for going second siding out fiendsmith stuff, converting the extra deck pieces in target for metaltronus and slayer, during test hands i barely bricked and the deck feels super powerful if it manages to go, but ,even if you don't, the fiendsmiths help getting something on board when they stopped your mitsurugi combo or even baiting handtraps/interruption. Super fun deck and will absolutely take it to some locals, the build is definetely not final and can be improved and changed based on how the format develops. Hope this helps!
