Well, as i see 3 BOM in your deck id say WTF? Isnt that card limited?
Also to be honest, an OTK tactic with this deck is not so good as it can never be fast enough for that. What is the tactic for OTK here, you can summon only 1 high level worm on field in 1 turn. The SOH wont help you much there. A better tactic imo is to make a control deck since the worms have a lot of such effects as destroying cards or sending them to hand or grave.
Also i just saw you posted the deck in January when the olf banlist was used. The deck is kinda too old o.o
