Hi!! I dunno if you remember me, but I definitely remember you, arcanine612!! I don't really remember your other username, Monster, but at least I remembered your name when it was arcanine612!! lol Welcome back to TPM!! I hope that you decide to stick around for awhile, it's nice to see you back again!! ^_^
Snorlax-Very good, you could go with Curse instead of Earthquake, it can work pretty good, powering up Body Slam and SelfDestruct. Fire Blast could be used as more of a surprise move then, since a lot of people will assume that your Snorlax will have Earthquake along with Curse. But, in all reality, either move will work.
Espeon-Moveset is great. However, since your Espeon doesn't use any moves that are dependent on it's Attack stat, you may as well use a female Espeon. The only reason is for protection against Confusion and Attract. Females have lower Attack DVs than males. (This only applies to Pokémon that can be both male or female) When you have a Pokémon that doesn't use it's Attack stat, it is best for it to have an Attack DV of 1, (an Attack DV of 1 is better than an Attack DV of 0, because if you have an Attack DV of 0, then you will be unable to have max HP.) so it will do less damage to itself just in case it hurts itself in Confusion. It is nothing major, but every little bit helps IMO. Also, you won't really have to worry about Attract, because just about every Attracter is female.
Zapdos-Excellent moveset. Just watch out for people that consider HP legendaries "cheap."
Blissey-Standard moveset, very good.
Kingdra-Again, great moveset. Ice Beam also works good instead of Dragonbreath, but either move will work nicely.
Donphan-Terrific!!
Overall-Very impressive team!! No 3x weaknesses, all of your movesets are really great. I don't really see anything at all wrong with your team at all. Great work!! And once again, welcome back!!
