This game is very corner based for some of the characters. Blaziken, Lucario, and Gengar all have corner only combos. Lucario seems to be an interesting mix of Yun and Ryu, and has some very powerful corner combos. Same for Blaziken, and burn seems a little too much.
Edit:
Combo Examples:
Lucario (corner): lp,lp,qcb hp,f+hk,qcb x2 hp
Blaziken (corner): lk,cr. lp, cr. lk, qcb hk
throw, lp, lk, hk
