The goal should not be to take Prizes.
In this aspect I find Twins to be a very good choice for Durant decks.
My own take on it:
4x Durant
2x Mime Jr
2x Sneasel
2x Weavile
2x Rotom
4x Pokémon Collector
3x Twins
2x Seeker
2x Professor Oak's New Theory
4x Eviolite
4x Defender
4x Revive
4x Junk Arm
4x Pokémon Catcher
1x Alph Litograph (4)
4x Special Metal Energy
2x Metal Energy
4x Rainbow Energy
Sure, my list can't get T1 4 Durant in play unless I start with one, but it has enough disruption and mid to late game possibillities. If the early disruption won't work out, the Seeker, Pokémon Catcher, or even Weavile (a fresh one, or a just Seeker'd one) will keep messing the opponent up, while Durant keeps chewing.
The ''obvious 4x4 trainer line'' is included for obvious reasons: Eviolite and Defender to keep even the most fierce attacker at bay (as long as it isn't fire type), Revive to retrieve any fainted Durants, and Junk Arm keeps the entire cycle going, depending on what's needed, and when.
Pokémon Collector speaks for itself, the Twins allow for great search during the game, and PONT is there to give you the hand refresh Cleffa would have offered, but instead you can keep milling in my opinion. Besides, because Durant doesn't need a lot to set up, and your Twins will be doing their job, I think it's hardly needed to refresh your hand a lot; after you set up you just need to do one thing: Milling, and keep milling.
Rotom and Alph Litograph (4) are used to get any Durants you need from your prizes, but after 1 Collector you already know how many are prized anyway, so if need be you could just switch out your prizes ''blind'', as you know your odds of getting the Durant(s), but Alph is just there to be fetched with Twins should it be needed (chances you are giving up a prize anyway if you really got a bad setup and still need to fetch any Durant from your prize(s) is pretty big in my opinion?).
The energy line up speaks for itself; as long as you get any of the 10 energy in your opening hand, your Durant gets a clear go, but the Rainbow Energy allows your Sneasel, Weavile, and even Rotom the option to deal a little damage when needed, or when you are really in a pinch (or feeling lucky!) you could always go all-out with them to pull off a (sniping) sweep. I know the Rainbow Energy deals 10 damage upon attachment, and that if Sneasel were to use it it would only have 40HP left, but I find the pro's it provides overweighing the cons, and when you're in a pinch you'll grab anything to fight back, no?
