Who is the Strongest Pokemon?

[ZaP~]

Dragonite also is flying type, so has a 4x Ice weakness, not so good speed and a nice special attack if i'm not wrong
And Swampert has a 4xGrass Weakness, so even a Jolteon's hidden power can OHKO them...Swampert also has access to Curse and that may be the reason he is such a monster
The best pokemon, on the metagame i would say Blissey, is a monster...but so cheap
I, personally like a lot Salamance 2xDragon Dance and start KO everything, has a really nice movepool, high Attack Status and good Speed or Snorlax [Is like Swampert] but has a lot of more HP, more SDef, less attack and zero speed and also uses the classic Curse/Rest/insert 2 physical moves here
