I'm generally a mixup player type, but those in general don't come alone, the characters i main mostly are backed up with a average neutral game on their own, my historic fighting game data confirms that, and i was good at all these games due these characters
Tekken: Jin, Kunimitsu
MK9: Skarlet
SF4: Ibuki, Decapre, Cammy
Last Blade 2: Moriya Minakata
Samurai Shodown 2: Haohmaru
Samurai Shodown 5 Special: Sogetsu Kazama, Kazuki Kazama
SF EX2 plus and ex 3: Shadow Geist and Doctrine Dark
Soul Calibur 2: Killik, Talim
MK Trilogy: Ermac, H Smoke, Scorpion, Raiden
Also, knockdown game can resolve around anything, these includes mixing characters up on knockdown with meaty setups safe jumps anti wakeups etc etc
