Its a bad combo.
Not because they don't work well together, but because:
1. Dusclops is a coin flip. If you want a coinflip for spreading, go for Zapdos.
2. We have much better options. Prinplup DP, Vibrava SW, ect.
Go for more reliable spread than Dusclops, Prinplup works well. Vibrava even matches your energy type.
If your going to go Water then Go Fossil. Omanyte, Omastar & Aerodactyl will help out better than Prinplup. This is my choice and dose well.
Omanyte (MD) - Call Other Fossil and spread Damage (Better Than Prinplup).
Call Up - Once during your turn (before your attack), you may flip a coin. If heads, search your discard pile for Helix Fossil, Dome Fossil, or Old Amber and put it onto your Bench. This power can't be used if Omanyte is affected by a Special Condition.
Wash Over (20) Does 10 damage to 2 of your opponents Benched Pokemon. (Don't apply Weakness and Resistance for Benched Pokemon.)
Omastar (MD) - Spread Damage 1st then Devolve for KO which helps Kabutops.
Primal Swirl - Once during your turn, when you play Omastar from your hand to evolve 1 of your Pokemon, you may remove the highest Stage Evolution card from each of your opponent's Benched Evolved Pokemon and put those cased back into his or her hand. You can't use more than 1 Primal Swirl Poke-Power each turn.
Aerodactyl (MD) - Places Damage when using Poke-Power which helps Kabutops
Primal Claw - After your opponent's Pokemon uses a Poke-Power, put 2 damage counters on that Pokemon.
