That's a match I have just had. The guy with the Liepard team was pretty good, I think someone else on this thread had battled him already (I don't remember who, sorry)
I think I made some good plays during this match (thunder wave on Lopunny, switch toad into Whirlwind, etcetc). Anyways I lost. Assist had only 4-5 PPs left I guess, and the poison crippled my Seismitoad in the end. I agree with Lasagne21, the only way to stop this Liepard is using a faster priority user or outspeed Liepard on the switch. That's not simple anyway, as I can't think of a SR setter faster than Liepard, maybe Swift Swim Seismitoad under rain is the only one (turn 36)
That's not the first time I have seen this team on the ladder, but nobody knew how to use this team efficiently like this guy did.
If I get the reqs for the vote, I'll most likely vote to ban Prankster+Assist (I don't want to say again all the reasons, it's the 11th page of the thread, I think people understood them)
This epitomizes why Liepard should be banned. You played really well during this and the other guy actually played like shit (taking 20 turns to predict the Seismatoad switch-in, going out to the paralyzed lopunny so he'd switch after Seis so he couldn't copy rocks, etc.), yet he won regardless. I don't see how you couldn't vote to ban Assist + Prankster at the very least.
