First time I played Pokemon Diamond in 2007. I had not yet gotten into competitive battling yet and I was still shaky at type matchups. When I was fighting the Elite 4, I couldn't tell what type Aron's Drapion or how to counter it. After 2 days of being completely swept by it, I finally found that it is weak to ground type moves. The only ground type move I had on my team (again, I was a noob) was EQ from my Torterra. I switched to my trusted started as soon as Drapion reared its ugly head. To my surprise/shock/super-rage, the blasted thing knew Ice Fang and OHKO'd my Torterra. I did the only thing a then-middleschooler would do; ragequit and not touch the game for a week.
