As promised, I'm here with a pic and info on my team now that I lost.

- Substitute
Really would've liked more opprotunities to switch this in (since I usually only need a few turns of set-up rather than the 10-11 it takes Registeel, counting 1 broken sub) but Cresselia just doesn't get the wanted fighting or ground moves thrown at it.
Registeel @ leftovers

EVs: 252 HP / 4 Def / 252 SpD

Registeel & Mence work so well together, covering each others' weaknesses. It was always easy to find switch and set up. I didn't run into too many OHKO users, but things like T-wave Jolteon were more of an annoyance.
My final downfall came (sorry I didn't check the trainer name) when I was against a Suicune. I tricked its Surf, then paralyzed it. I Flashed until it KO'ed me and Registeel was easily able to fully setup. I started to chip away at its HP, with IH, had gotten close to halfway when my opponent switched to Heatran. Of course the first Flamethrower broke my sub & the next one burned me before I could set it back up. I was finally able to KO Heatran with weakened Iron Heads, and then Suicune came back out and started used the last of its Surfs, before struggling itself to death at the same time the burn took Registeel away from me. So I was left with Salamence one on one with Articuno. I sub'ed, hoping I'd get a free turn, but the subsequent Ice Beam took me down when my Outrage only did ~70%.
