Replace Negodz with Cyb or C Wing definitely. Replace Rudy with Norman. That's my suggestion. People will say replace Oflgn, but he's a good, under-used card that can create a massive life gap and keep your opponent in check. Good synergy with his bonus too.
Negodz is flat-out sub-par. C Wing could be your defeat card instead of Rudy and Cyb's poison would mesh well with Oflgn. Rudy is good for a surprise attack every once in a while, but short of that he's very predictable and is really hard to have a use without his ability. Norman only has one more power, but it makes a lot of difference. His ability doesn't matter if you use him third or last round and it can get canceled out by SoA as well.
I've made some changes, based on some of the suggestions and it's got me up to 1200 ELO so far, along with another one of my decks.
Updated deck is:
Elvis - Lola - Kostner - Roger
Oflgn - Bublgmm - Neloe - Dreadlash
