Shirai Ryu is the best Card, make sure you upgrade those whenever you can, his heavy string (low, body blow, Sword), the second hit gives plenty of frame advantage that you can do an infinite on every character who gets hit by the low, keep looping, the first two this, then give a waiting period, before your character fully recovers, repeat the process, if you do this correct no character in the game will be able to block, and you can survive many tedious matches where you're forced to do a bunch of craps, like feeling special attacks.
Just, set your Shirai Ryu to land the heavy string and you're good to go, Tap Tap, Wait , Tap Tap, Wait, Tap Tap, Wait ... until their lives reaches zero.
Just be careful against the opponents team, this tactic builds up their super too, i use mostly to take out hardass bosses like OP Reptile, or Cheap ass Kotal etc.
