More Battle Subway. More "fuck weavile".
I send out Volcarona. "Ha," I say. "I'm a full health, you can't one shot me." It uses fake out, crits, deals half my health. Next turn it uses night slash, crits, gets the other half. So I send in Cofagrigus, land the Will-o-Wisp, then switch to Sawsbuck. I smack it down with Return at the cost of most of my health.
She sends out Steelix. Easy, right? I use horn leech, but the Steelix outspeeds me and uses night slash. What the fuck. I hit it, revealing it as a Zoroark. Yay, she managed to get two Weaviles on her team! I try to kill it with Return but it crits on Night Slash and kills me.
Only Cofagrigus remains. I go for the Will-o-Wisp, and manage to burn/hex it down with like 20HP left. Then the real Steelix shows up. Its strategy is curse+chestorest with its only offensive move being Earthquake. Luckily I have Haze to render its cursing useless, and Will-o-Wisp to ensure that its earthquakes can only deal like 14 damage at a time.
I heal slowly off leftovers but realize that I can't kill it if it keeps using Rest, so I curse it while it's asleep as soon as I break half health. I immediately realize it's impossible for me to Will-o-Wisp it on the turn it wakes up. It uses earthquake, which deals like 28 damage and kills me.
Moral of the story: fuck dark types and fuck lucky crits.
edit: And another round! I wipe this dude's team and my Pokemon are damaged, but nothing ridiculous. Then his last pokemon... WEAVILE! It outspeeds my Cofagrigus, takes down the rest of its health. Outspeeds my Sawsbuck, killing it in two hits while Sawsbuck takes it down to like 3HP, then outspeeds my Volcarona and one-shots it. It didn't even need to crit. I need some fucking priority moves.
