Ha ha, wow, these forums have impressed me much more than I had thought they would, seeing as how there's even a thread about Jump Ultimate Stars. It's CRAZY!!!
Anyway, I've started to ween myself off of Jump after 3 months of addiction, so I don't want to jump back in...
BUT! Let me just say this. The ULTIMATE DECK, to counter even those bastard 3-Koma Trunks and Seiya, your asshole Sasuke's and Bankai Ichigo's, is the following:
4-Koma Robin: We want this deck to be hawt, and Robin almost makes it too hot. Almost. (Also, she balances out the deck by being Knowledge type and boosting Sanji, but that comes second to her sexiness.)
6-Koma Sanji: Because we actually want this deck to kick ass; Sanji guarantees its kickassery.
4-Koma Nami (Laughter): You DO like to win, right? Yum, taste those special bars, bars that COULD have been used for Trunks and Seiya, which now can be used for Aya, who will only FURTHER drain energy bars and actually lock off Trunks and Seiya (as if they had special bars anyway).
2-Koma Aya: Drains one special bar, locks off supports, combo-able, can be used as a counter... Essential.
1-Koma Eve and Yoruichi: Attach to Sanji for maximum pwnage.
Any Other 2 Female Help Koma: Whatever floats your boat, so long as its female, thus boosting Sanji's hormonal steroid pumpage pwnage factor (AKA Up + X).
Use, abuse, kick ass, and show cheapasses who's boss online. When you start to get hit in a combo, hit 'em with Aya, and follow up with a Sanji combo + Veal Shot (his X special). Use Nami to steal special bars when you're low on Aya's, and you're good to go.
