>>13269714>HydreigonEasily my favorite Gen V Poke. Superb coverage from a hugely diverse movepool, really cool typing, decent defensive capability with resists to Fire, Water, Elec, & Grass combined with not paper-thin defenses, and a cool look to boot. I did my run of Black 2 with a team of my favorites a few months back, and while everyone else was easy to evolve due to access to stones and Audino grinding, Deino was left behind for quite a while. It wasn't even a Zweilous until I fought Marlon. But goddamn if there isn't something rewarding about having Hydreigon to nuke the Elite 4 with.
>SwampertThe thing I like about competitive Pokemon the most is the versatility of a given Pokemon; if it can perform multiple roles and adapt to the situation, and Swampert definitely fulfilled that balance, capable of going mixed offensively with Earthquake and Ice Beam, and acting as a pivot against both spectrums. I chose Mudkip in my first run of Sapphire when I was 10, and it was my first pokemon I ever managed to grind to 100.
