try a K-RAZ mini swarm vs any combo of "Space butterfly" my money is on the K-raz!!
Not too familiar with the K-fighter mini-swarm, but I'm in love with Guri with LW, AT, SJ. She's super-tanky. You can throw in Glitterstim to just be ridiculous. If you fly her well enough she'll be throwing 4 dice at her target and get her auto-focus. I think she'd be broken at a higher PS.
