Nice deck. I would personally change Miss Stella to SkrumxxT.
Or change Zatman to Stella imho. That way you have better synergy all around to threaten 2HKO with any of your other cards.
SkrumxxT would be my 2nd choice to switch with Zatman because he is somewhat susceptible to SOA compared to the others in the deck, and having 3 damage would lessen your 2HKO potential even more.
