For me it was my Lucario, having tutored it ice punch it was pretty beast at getting one hit ko's plus it's steel type advantage gave it a lot of resistance to dragon type moves. I also used my ampharos alot, with its echoed voice attack, as it could take a lot of hits and once it had use echoed voice about 3 times, it was straight on 1 hit ko's from then on
