Please feel free to leave any comments and suggestions on changing any moves and/or Pokémon.

Many thanks in advance! c:

Just so you know, we need to see the EVs and natures of your Pokemon, not just their stats. :/

Anyway:

Despite the fact that Seismitoad's stats are balanced, its special movepool is better than its physical one. Seismitoad's current stats also don't match up with its moves. I believe this set would be good enough?:
-Rain Dance
-Hydro Pump/Surf
-Earth Power
-Sludge Wave/Hidden Power (Ice)
Nature: Modest
EVs: 96 HP/252 SAtk/160 Spe
Item: Life Orb/Damp Rock
Ability: Swift Swim

Also, Seismitoad is outclassed by Kingdra as a Swift Swim sweeper because the latter has higher offenses and Speed:
-Rain Dance
-Hydro Pump/Surf
-Draco Meteor
-Surf/Dragon Pulse/Ice Beam
Nature: Modest
EVs: 28 HP/252 SAtk/228 Spe
Item: Damp Rock/Life Orb
Ability: Swift Swim

Hyper Beam-style moves are generally frowned down upon competitively because of their recharge turns. Also, Emboar seriously needs more coverage, since Fire + Normal don't cut it:
-Flare Blitz
-Superpower
-Wild Charge
-Head Smash/Stone Edge
Nature: Adamant
EVs: 128 HP/252 Atk/128 Spe
Item: Choice Band

Generally, Emboar is outclassed by Infernape because the latter is faster and has a wider move pool:
-Overheat/Fire Blast
-Close Combat
-Grass Knot/U-turn
-Mach Punch/Stone Edge
Nature: Hasty/Naive
EVs: 252 Atk/4 SAtk/252 Spe
Item: Life Orb/Expert Belt

While Simisage is fast, its defenses are poor and its offenses are average at best. IMO, Ferrothorn would be a good replacement for its bulk and support:
-Stealth Rock/Spikes
-Leech Seed
-Gyro Ball/Thunder Wave/Protect
-Power Whip/Protect
Nature: Relaxed
EVs: 252 HP/88 Def/168 SDef
Item: Leftovers/Rocky Helmet

If you can go to the Dream World, get a Dragonite with the Multiscale ability, since that's the ability that makes it so good in OU. Also, moves like Fly/Dig/Dive are easy to avoid; the opponent can just switch in something to take the attack the next turn:
-Dragon Dance
-Outrage/Dragon Claw
-Fire Punch
-Earthquake/ExtremeSpeed/Roost
Nature: Adamant/Jolly
EVs: 252 Atk/4 SAtk/252 Spe
Item: Leftovers/Lum Berry
Ability: Multiscale

or
-Dragon Dance
-Dragon Claw/Outrage
-Fire Punch
-Roost
Nature: Adamant/Jolly
EVs: 252 HP/44 Atk/212 Spe
Item: Leftovers/Lum Berry
Ability: Multiscale

Let's face it; Lunatone sucks. Seriously. Because of its somewhat average stats. Reuniclus is a better alternative because of its bulk and higher Special Attack:
-Calm Mind
-Psychic/Psyshock
-Focus Blast
-Recover
Nature: Bold
EVs: 252 HP/252 Def/4 SDef
Item: Leftovers/Life Orb
Ability: Magic Guard

or
-Trick Room
-Psychic/Psyshock
-Shadow Ball
-Focus Blast
Nature: Quiet
EVs: 192 HP/64 Def/252 SAtk
Item: Life Orb
Ability: Magic Guard
