I've had little issue using my standard catching brelooms. Come into the battle already poisoned, spore turn 1, sub turn 2, chip away while spore+subbing when necessary. My brelooms are level 80 though so for scenarios like ghost types where I can't false swipe, their seed bomb/rock slide is a viable chip option. Not sure if that'd still be the case if they were level 100. Tbf I've also had good luck on alphas lately, been at least 8 alphas since I've needed more than 3 balls for the catch.
