hi, i love aggron, so natrualy i had to build a deck for him. I was debateing for a long time weither to build it with the xatu as back up or use wailmer/lord to cover my weekness. Both of the decks looked promising and i couldnt choose so i built both. See i love my decks, its more of a hobbie for me to just have a deck, weither i play it or not. I look at them as works of art belive it or not, and it is VERY hard for me to tear apart one of my works ( the reason i always hate when modified gets modified LOL) my current deck count is at 24 and they are all fully suported with a good trainer engines ( a feat in its self) i just cant bring myself to take any of them apart, and i consider them all very good and unique decks. Now onto your deck.
When i first made the two decks i used a 4/4/2/2 line of arron/laron/aggron/aggronEX and also a 2/2 furret sentrent line to get the metal energy of course, and found it to work pritty good. The idea is that you build up an aggron ex, attack as much as you can, get some real good bench dammage in, mean time builing an aggron. Now the aggron is good back up becuase it has a cheap attack a middle attack and a huge attack so it does not have to be fully powerd up in order to attack and send out
What i found, well first lets look at the wailord vareint. I found that trying to build a waillord and a aggron on the bench at the same time proved to be a waist of time. While i originaly intended for the wail line to be used as weekness protection i found it served as a very good general backup line also. The regular aggon was not needed.
With the Xatu varent, i found it much much more eveadent that i did not need the other aggron, infact here it impeeded me. See in this deck i shifed focus of the stratagy. See i would still try to get the aggron ex out first and power it up and use (i think this is the name) metal surge as much as possiable. Worked pritty good as i would get it off normal like 3-4 times with the ultra heal of xatu, netting me about 3/4 prizes on bench damage and direct damage alone. If they ever did knock out the aggron; the xatu, a most formiable attacker in its own right, would finish with great bench damage of its own. This attack is often overlooked, as with your opponent having a full bench a xatu can shoot 60 dammage for 2 energy, its just really spread out. Also unless you OHKO the xatu, you can menagle them arround with there free retreat and eventualy heal them back to full heath.
so in the end i did not like the aggron, and i droped it all toghther for a 3/3/2 line of arron/larron/aggron EX. Having one ex line in your deck is not bad, your opponent may knock out the aggron ex, however you should get 4 prizes atleast with it makeing it more than worth while.
now lets look at your trainers
4 Power Charge
4 Switch
4 Mr. Briney's Compassion
4 Professor Oak's Research
4 Potion
3 Fast Ball
1 Town Volunteer
hummmmm. ok im assuming that you like my xatu theme and going to agust the trianers to suit that theme, now first let me say that even with trainers ment to be dedicated to a certian theme that peoples play styles affect the trainers A LOT, i could have the exact same pokemon as you in a deck, and we could have the deck set out to do the same exact thing, however have the trainers in those decks be completely diffrent.
ok sooo power charge, yea since we will most likely only be seeing one aggron ex in play and trying to load it up with all 4 metals and when it gets knocked out letting that be that, im going to drop the count to 2, now going with the odds that should let you get atleast 2 metals back during the game, now i know i said that once aggron ex is killed its killed but... you never know when a metel or 2 might be good on a larron heck it might be all you can get out and it is just good to have the opption.
i cut the switch one, the britnys compassion by 2 changed the oaks research over to birch and shamman, now this might need some explaning. Normaly i preferr Oaks R and copyCat to birch and shamman, however not in this case. Any deck with furret NEEDS birch, it is just awsome. Furret will often leave you with one or none cards in your hand, with all the 2for1 NRG exchanging it does. so then laying down a birch will draw you a fresh hand of 6 which ROCKS, try it you wont be dissapointed. And since you will be haveing a low hand count anyway why now add desert shamman, for the hand disruption you can play on your opponent. You sack one card from 5 to 4, in using shammon over oaks research however you get to screw with your opponents hand as well. LOL its so funny sometimes, my favorit is when they have the call for family wirple active and search out and get cascune and dustox in there hand and then next turn i lay a shamman and you should see them wine its so funny. Anyway, back on topic the birch and samman AVG out over 2 turns to be a 5 card hand anyway so you are not really losing anything and the top deck draw and opponent hand disruption are like little boneses, and we LOVE boneses. A general deck building tip here, you should always have more than 4 of card drawing in your deck, now every deck is diffrent (this is not like oak or elm) and you should have atleast 7 of the following, oaks research, copycat, birch, juggler, or shamman now im not counting oracle cause thats a card specific search card. O yea and on another note, dont mix copycat and shamman they have oppsite directions of interest, one trys to get your opponents hand larger and the other keeps it small, trust me dont play those 2 toghter.
kept the 4 poton, the fast ball (although you might want to play elms traing method, cause with this many evos it is chance you will get what you need, on the other hand it is a supporter and uses it for the turn, your choice, i prefer ETM) kept the 1 TV, and on second thought (cause i recounted my deck total) im droping the energy charge.
