TCGDeoxys, I don't know how experienced you are with this game, but please understand that a lot of us are trying to be gentle with you... and your resistance to what we say has just kept this going long enough it might justify taking off the kid gloves. You don't have to like what we are saying, but that doesn't make it incorrect.
First of all, TDK is only special energy! 4 Plasma, 4 Prism, 4 Blend WLFM.
Reference? I don't remember that being considered an intrinsic part of the deck. Certain builds? Oh, yes they ran only Special Energy. This isn't quite the same as a "Haymaker" deck, where the term was used not only for a specific actual deck built around
Hitmonchan (
Base Set) but also for the approach of using only Basic Pokémon with low Energy attacks or built-in Energy acceleration, multiple attackers for Type matching plus disruptive Trainers. Hmm... I'm starting to understand why people so many years later are confused about "Haymaker". XP
So... a few key basic Energy cards is now considered typical for a good TDK build.
I couldn't get Keldeo because no one would trade it.
Keldeo-EX has had multiple releases, including one in a collector's tin, didn't it? Doesn't mean you could find someone willing to trade or afford to buy it, but it does mean that it isn't excessively difficult to obtain unless you have really restricted resources... and if you have really restricted resources, then it isn't fair to ignore than and claim "Card X is broken!". There are times when there being an extremely hard to obtain but otherwise widely played answer is not a "legitimate" counter, but obtaining the card must be difficult for the general playing public. A good example was
Tropical Beach, though not countering anything it was useful and considered an important part of some very good decks, but both the overall card supply and the capacity for people to get it without buying from others was significantly constrained because it was a Worlds promo, only available to those who attended Worlds during an appropriate year.
So... missing piece is missing.
Malamars also only need 3 energy to knock out everything I have.
Welcome to Pokémon!
...
Sorry, but yeah, top attackers can do
amazing things with three Energy and generally have been able to for the game's entire lifespan. OHKOing something with 180 HP hasn't been as common until recently, but now you expect three Energy attacks to at least set-up for a 2HKO reliably. "Reliably" is also important;
Malamar-EX can score a OHKO of something with 130 to 180 HP, but with no other buffs it needs to flip three "heads". That is only one out of eight outcomes or a 12.5% chance: the odds of that are the same as the odds of it whiffing and doing no damage whatsoever!
Kyurem [Plasma] is a 130 HP Basic Pokémon that for three Energy can swing for 120 damage. With
Muscle Band or
Silver Bangle and
Deoxys-EX, it too can OHKO everything in your deck. 50 less HP, but worth one less Prize. It has the drawback of being unable to attack again the next turn but a good TDK has a way around that plus it only matters if
Kyurem [Plasma] survives... and if it survives it can try to do it again!
Plus, it is resistant to psychic.
A marginal advantage; Resistance is a well balanced mechanic in the Pokémon TCG... which means when it comes to competitive play it is rather under powered. Weakness on the other hand is insane as it flat out doubles the damage done.
