What you can do to counter gengar is impersonate a cyrus to grab a collector. Next turn, you collector for magikarp, magikarp and regiice and then your doing 60-80 right there. I may also tech in absol G because with a SP dark, your OHKOing gengar prime, and they dont have that great of a way to kill it. Having cyrus also helps set this up, plus the SP darks can let you donk with sableye.
