Woa. Woa. Woa. 20 Water Energies? That is way too much. I'd suggest taking it down to 14 water energies at maximum. The reason I say this is because that many energies isn't needed one bit, plus it heavily subtracts your consistency level. Also, you play 20 energies! That's a ton! Heck, 14 energies is a lot! Maybe you should take out Cilan, and just stick with the Interviewers' Questions because of this (Heck, personally, I'd rely on hand refreshers such as Professor Oak's New Theory and N to help me get my energies)? I also should note that the Simipours and Panpours are NOT needed for the strategy that you are trying for in this deck, and perhaps you should play Mewtwo-EX instead (which would help a TON, especially to counter opposing Mewtwos). They also abuse the constant energy attaching.
Also, the 2-2-2 lines that you play in this deck are too thin, especially for the Feraligatr line, which is what your deck focuses most on. By taking out some of the unnessary Pokemon in this deck, it would be a wise idea to bump up the lines a bit. Also, I should note that Blastoise from Unleashed does a much better job at attacking than Samurott does. If I were you, I'd change this deck to a Blastgatr focus (but still constant attaching of energies, as I see you like). One thing that Blastoise can do excellently is against The Truth, it can one-shot a benched Reuniclus by quickly sniping it down. It can also two-shot any Vileplumes that your opponent has benched, and it pretty much acts as a free Pokemon Catcher (that is not used to stall, that is). From the fact that Blastoise can 2-shot ANY EX that is in play, it more or less is going to see plenty of play eventually (plus the fact that Mewtwo-EX does everything Samurott does, except better).
I can also see that you are missing many staples such as Pokemon Collector, Rare Candy, and the 4 Pokemon Communications that you should be playing (2 is not enough). If I could take out some unnessary Pokemon and add these, your deck would be much faster and more consistent.
From everything I said above, here are the changes that I would reccomend for your deck:
-6 Water Energy (Overall Consistency)
-3 Level Ball (Collector gets out basics better)
-2 Interviewers' Questions (Consistency)
-3 Professor Elm's Training Method (Pokemon Communication functions as a better way to get evolutions out)
-3 Fisherman (Not needed, though Super rod is much better)
-1 Cilan (3= ruins consistency)
-2 Panpour (Irrevelant to this deck's strategy)
-2 Simipour (Irrevelant to this deck's strategy)
-2 Staryu (Irrevelant to this deck's strategy)
-2 Starmie (Irrevelant to this deck's strategy)
-2 Samurott (Mewtwo-EX is a much better version of this)
-2 Dewott (Because of Samurott)
-2 Oshawott (Because of Samurott)
+3 Squirtle UL (For the Blastoise)
+2 Wartortle UL (For the Blastoise)
+3 Blastoise UL (To cover your weaknesses)
+3 Mewtwo-EX (A better and quicker version of Samurott. It can also counter other Mewtwos)
+2 Pokemon Collector (4 is always a staple to get out basics quickly)
+2 Pokemon Communication (For consistency, especially in combination with Rare Candy)
+4 Rare Candy (To get your evolutions out very fast)
+2 Totodile (Consistency, and as a just in case because of Pokemon Catchers)
+2 Feraligatr Prime (Consistency, and in case one is prized)
+1 Kyurem-EX (Quick attacker in combination with Feraligatr, and gets rid of DCE)
+1 Super Rod (To get back your Water Energies from past attackers)
+2 Professor Oak's New Theory (So you can get a better hand when you need it, while getting more energies at the same time)
+2 Twins (Just in case one of your basics gets KO'd early game, which can happen a lot with this deck - trust me)
+3 N (Disruption + Hand Refreshment? Yes, please!)
Overall, from the above changes, your final, perfect list should look like this:
3x Squirtle UL
2x Wartortle UL
3x Blastoise UL
4x Totodile GS
2x Croconaw GS
4x Feraligatr Prime GS
2x Kyurem NV
1x Kyurem-EX
3x Mewtwo-EX
4x Pokemon Collector
2x Cilan
4x Rare Candy
4x Oak New Theory
4x Pokemon Communication
1x Super Rod
2x Twins
3x N
14x Water energy
Hope I helped, and good luck with your deck! :]
