Poison her with an aphrodisiac

After working in your lab for a week you have successfully formulated a potent aphrodisiac and muscle relaxant, keyed specifically to the Luv genetic code. Tests on Rachel and Pam show its only effect on normal people is light arousal, on a Luv it will not only weaken the body's ability to respond, it will also aggravate stimulation fourfold.

Driven by this revelation you quickly begin plotting, Mama Luv will soon be defeated. You concentrate the formula imto a small compressed gas pellet which you sneak into the lab coat you wear to matches.

Soon your number's up, after a solid month of planning its time for your match.
