It is in the sense the energy costs are low (1 Fighting 60 damage) with the Alts extra 20 its 80-100-120 on average
or (1 FIghting 1 Water) for 100, Alts making it 120-140-160 on average
This damage is normal to find on EXs and other highly used pokemon such as Zekrom or Raikou, Mewtwo or Darkrai.
but ofcourse it comes with out the EX burden of 2 prizes.
biggest down sides being its type and HP
140HP is respectable and withstands Zekrom or Darkrai(+ Claw if used) without the need of Eviolite (not that he could use it anyway)
Typing is one of those 50-50 things with his weakness being himself (Dragon).
We will see ALOT of dragon play as they are new and exciting cards so its going to be a little short there at 1st.
The deck itself is whats powerful tho, the ability to search out the Dragons with such ease is amazing (once Gabite is 100% confirmed).
Does Garchomp deserve the Hype? no, but you didnt ask that
Does the Deck deserve Hype? Yes! 100%
It has what any good deck needs right now, power and speed, the ability to withstand a Darkrai hit and to not be dropped by Terrakion.
Ofcourse saying all this is in its simplest form, Darkrai hitting for 30 before hitting for 110 (Dark Claw) is the exact amount needed to kill one.
but Darkrai can play Eviolite just as well as it plays Dark Claw (if not better) so 30+90 isnt enough.
The deck itself has flaws in the form of Altaria having only 70HP making it weak to
Raikou-EX (100 damage Snipe)
Pokemon Catcher (almost everything in the game is weak to this tho)
Ray (40 Damage for 1 energy attack with type advantage = 80)
but unless played badly or having very very very very VERY VERY bad draws, you will not see an active Altaria during your opponents turn very often.
so that just goes back to Pokemon Catcher (alot more weaknesses with having a 70HP Dragon Type, but i assume the point was made)
All in all tho, the decks strengths out play it weaknesses (have tested this for the last 1-2 months against everything i could think of)
Biggest flaws im seeing in builds are
3-3 Altaria, someone mentioned it above i think 4-3 Line is better
4-2-4 and 4-3-4 Garchomp, 4-2-4 is just plain wrong, but i have seen it in a builds, 4-3-4 works, but with my testing im finding 4-4-4 works best.
when people work out how to play (or they may know already) against it, killing off Gabite quick! is a must. so you find atfter turn 2-3 you should have lost 1-2 Gabites and only have 2 left in deck (not counting Super Rod play).
flaws i have seen in play of this deck
People playing Super Rod early or on cards like Garchomp, Use the Super Rods more on the Altarias and when needed then move onto Garchomp (need Garbite is the exception to this)
Feeling like they need to play a Supporter EVERY turn (this is something you see wrong with other decks), just because the ruling is 1 supporter a turn does NOT mean you MUST play 1 a turn (not saying people think this, just how they play it). Seen so many supporters played while i was on the defensive and they have decent hands. Its not needed especially in this deck, the deck draws itself out and gives you everything you need.
My final note is
Plus Power (i normally do not like this card)
Garchomps attacks work in 20's (60 and 100) with boosts of 20 (Alt)
Terrakion 130HP, Zekrom 130HP, Mewtwo-EX 170HP, Raikou-EX 170HP
If you have the room it can make life alot easyer (but again, im not a Plus Power fan normally)
