Source? I've never heard this one.
As for my getup
KOTR or Master= Quadra
KOTR or Master= HP absorb
Counter= Mime
W-Summon
Hades
W-summon Hades then KOTR. A stopped Ruby is a ruby that can't counter. And if it does come out of stop mid attack and counter, you'll live and counter mime, and be back at full.
Just cast it once and mime to victory.
