2. 1-9 (whole match, it's not long. Would've been win in 10 but they surrendered.)
3. Dankest spinblocker of all time.
To add a little color, mega-stoise was considered to be both a fantastic mon and the only really good remover (or at least the only good spinner, since Donphan's greatness wasn't yet recognized), making him near-mandatory. He also typically ran (and still runs) stabless with spin/dark pulse/aura sphere/ice beam, so the standard set can hit drifblim either super effectively or not at all. Drifblim survives due to general fatness and carefully-crafted EVs, then gets both WP and unburden boosts. It usually just gets killed by priority shortly afterwards (which is fine because spinblocking is his real job, the rest is just constraining what the opponent can do via threat), but it got to have a bit more fun this match.
