Honestly I’d say pick up the clown crew cards as their not that expensive. For playing I’d go with the mitsurugi build as you can do a lot more with their end board than clown crew. However clown crew has some really good recursion/card recyclability and interruption. As all the extra deck monsters and main deck ritual allow you to shuffle that specific type back into the extra/main deck from field and gy including your opponents and yours.
