She's a hard fight for most of the roster, but specifically super heavyweights with slower moves against Christie. That shit is a journey. Try playing Bass, Raidou, or Leon within terrible net matches where you are trying to interrupt fast strings on block with fast block stun recovery.
Any Lisa is a hard fight for me. For the life of me I can't fight her at all. Even button mashers give me a hard time lol. All that jumping around with a mix of attacks and OH's just makes me get a a deer in a headlight look lol.
