M Aggron is pure trash sorry. I tried to make him and I couldn't, even with help from others. He's way too slow to get setup and even if you do, his attack is too inconsistent.
I have to disagree with you. I also tried to make an
M Aggron-EX deck and it never turned out very well... no, that isn't the same as "pure trash"; pretty clear we are trying to discuss things in more detail so if that was just a simple case of hyperbole, it was ill timed. The reason
M Aggron-EX isn't worth playing is because for all it has going for it
(just a quick rundown)
- 240 HP
- DCE compatible
- Spirit link
- variable attack that hits key amounts for OHKOs and 2HKOs
other stuff just does it
better. No, just because some things are better doesn't make a card pure trash; there is more to it than that because so often there is always something better.
In this case, it is the fact that the resources required to make
M Aggron-EX competitively fast and/or reliable are better spent on different attacks. A
Double Colorless Energy and two copies of
Mega Turbo take
M Aggron-EX from zero to attacking in a single turn Megaton Slam in a single turn... but you could use a little less than that to prep
M Rayquaza-EX (Emerald Break version) in terms of Energy. Reliably preparing a large enough Bench for high HP OHKOs seems on par with the Megaton Slam coin flip. In fact, even with
Trick Coin or
Victini (Victory Star), filling your Bench after dropping
Sky Field is probably still more reliable.
Δ Evolution means you can do all that in a single turn, but let's ignore that for a moment.
M Rayquaza-EX would still be better due to the lower Energy cost and still formidable attack, which we have of course seen borne out in competitive play. So yes, when
M Aggron-EX can set-up, it proves pretty nasty... but getting it to set-up in a reliably, timely manner and keeping it set up, plus the potential for the coins to turn against you mean it isn't unplayable, it isn't trash and it isn't underplayed. It just is a functional but not significantly competitive deck. It shouldn't win an event or even come close to making the top cut, but underestimating it or only a small bit of luck can still allow it to take a win against someone who otherwise was headed for the top.

Yeah, I've been that guy, knocked out of the running by something he casually dismissed, hence going on about the matter. ^^'
Note: Yes, I royally messed up and suggested using
Wally on a Pokémon-EX because brain fail. Corrected that and also cleaned up the message a bit.
