Just played at Aldershot cities with durant, got 6th out of 31, missed a top 8 cut by one person, here's how it went for me: (PS the only person to 5-0 swiss was another Durant player)
Game 1: Mirror Match
Both started w/Cobalion, I managed to set it up quicker, catchering up durants for cheap prizes, and lost remover/hammer on the cobalion. 6-0 in prizes
1-0
Game 2: ChandyPlume
Worst start I've ever had with the deck. Single Durant, Twins, Revive, and 5 energies as my first 8 cards.
My opponent gets a T2 Chandelure and T3 Vileplume. I'm pretty much stumped and lose.
1-1
Game 3: Reshiphlosion
Durant's worst matchup? K.
Opponent feels that the way to go against Durant is trying to set up as many cyndaquils to typhlosions as possible.
I respond to this by milling his resources for the first few turns while I set up cobalion. He KO's Durant with quilava and I revenge KO with cobalion. There on out he does minimal if any damage to me with reshirams, and I keep killing his cyndaquil's quilava's with catcher. It gets to a point where he can't play a cyndaquil down to rare candy next turn. I misplay though, and iron breaker the active reshiram. Of course out of 3 cards he has rare candy typhlosion, hmph. I Iron Breaker his Reshiram's requiring him to attach manually from his very small hand, and he draws Juniper. His only hope pretty much loses him the game as it appears he forgets what Durant does. I end up decking him with me taking 3 prizes and him taking only 2.
2-1
Game 4 : Zekrom/Eelektrik/Tornadus
I honestly thought Zekrom variants would be Durant's worst matchup, but luckily she played Eelektrik instead of ZPST. I get a nice mill going from T1, amazingly milling all her energies, and every time she attaches an energy, I crushing hammer or catcher another Zekrom. She can't possibly win, and I end up milling her with her not being able to take a single prize, even with only 3 Durants.
3-1
Game 5 : Reshiphlosion
Amazingly I play Reshiphlosion again, but he plays a much different strategy against Durant. Luckily for me he starts with Reshiram which makes me know I've basically won. First turn he Junipers 2 Typhlosions, which looking at his hand he had to do. I mill the 3rd, and he manages to like the previous reshiphlosion rare candy typhlosion with small amounts of cards in hand. I go down 2 or 3 prizes here trying to set up my strategy. I pretty much go on a Crushing hammer rampage discarding as many energies as possible, and then use my rogue tech, Seeker. Seeker brings up his Typhlosion, I don't think he has any candies left as he had 3 in discard and 3 junk arms there too, just in case I use N to minimise his chances. From here on out I stock up on eviolite and sp.metal withstanding the reshirams and retreating when damaged. It comes down to his last 3 prizes, and I need an energy to win, I use 2 pokegears in my hand to mill any useless supporters in my deck. Then I juniper, get the energy and win.
4-1
So I miss top cut on resistance because of the worst start I've ever had with Durant, and the chandyplume ends up taking 3/4th place. The 5-0 Durant also takes 3/4th place after a massive misplay in the semi's. My mate takes 1st with 6 corners, and D&D takes second.
So Durant can beat anything, unless you start with half your deck's energy in your hand.
