[Umby]

7 - Suicune
8 - Celebi
9-10 - Two of Dragonite, Blissey, Cloyster, Forretress.

Suicune's an excellent mon all around. I feel MD overrates it just a little bit, but no doubt it belongs in the #5-8 slot.

Celebi is Celebi. Even if we don't count it in second gen due to its uber status, having two gens worth of controversy (I recall talks of trying to ban Celebi some time during 3rd gen's hey day. Might have just been certain sites/servers, though) says something. It's a tough tank to break down and often requires specialized counters to prevent it from being a major thorn in the side. It's so versatile too. I'd honestly put it in 7th if I weren't afraid that M Dragon wouldn't murder me in my sleep.

Dragonite's the weird, overlooked guy. RBY it was a threat due to Wrap, but it's generally banned or there's a gentleman's agreement not to use it, so you don't see it constantly on the top of the RBY charts. GSC it was a dangerous mixed sweeper, but anyone who's played long enough can tell you that mixed sweeping isn't the end-all strategy to wall-breaking, thus it falls short of having a true dominance factor. Its other utilities are lackluster overall, for what it is. In ADV it was overshadowed by Salamence. I still think it has some potential, but the lower speed and lack of a decent ability hurt its standing more than one would first think. DPP saw it become a monster with physical dragon moves, for the mos obvious part, giving it its time to shine. Point is, Draggy has always been good on paper with solid stats and good moves. It just couldn't push the envelope to become a top threat until it got Draco Meteor and physical Outrage/Dragon Claw under its belt.

Blissey could get a spot for the same reason as Skarm, but it suffers more often from becoming setup bait for big offensive threats.

Cloyster vs Forry is kinda tough. I feel like Cloyster's viability (however varied) through out all 4 gens balances out over the the disadvantages it has against Forry when filling out the same role in gens 2-4.
