Magcargo EX Turbo Ground Burn

Turbo Ground Burn

Idea is to turbo Magcargo EX's Ground Burn live and stack as many energy as possible by using a combination of Charizard EX for energy setup, Lumineon V for searching key supporters & Ciphermaniac to guarantee energy on top. The rest of the deck is just to support the strategy or present alternative ones if Magcargo EX fails, such as pumping energy into Iron Hands EX with Charizard EX when going against a predominantly water deck et. al.

Charmander / Charizard EX / Rare Candy
Energy turbo for Magcargo EX, backup beatstick

Slugma / Magcargo EX
Primary strategy, stack energy & spam ground burn

Lumineon V
One card starter for turboing each strategy

Iron Hands EX
In-case turbo Ground Burn fails or a water predominant deck, Charizard EX can pump Iron Hands instead for easy KOs and extra prize.

Buddy-Buddy Poffin / Nest Ball
Poffin for finding Slugma/Charmander, Nest Ball for finding Slugma/Charmander/Iron Hands EX

Hisuian Heavy Ball
In-case key basics like Lumineon V or Iron Hands EX get sacked to prize

Ultra Ball
Search Charizard EX, Lumineon V or Magcargo EX

Magma Basin
Good for setting up energy on a benched Charizard EX in-case your Magcargo gets KO'd and you need an emergency backup.

Super Rod
For returning basic energy and key pieces back to deck such as Charizard EX. Good to use before using Ciphermaniac's Coderbreaking if you're out of basic energy in main deck.

PokeGear 3.0
Searches top 7 for any supporter, good for if you're missing Team Star Grunt or Ciphermaniac's Codebreaking.

Forest Seal Stone
Attach to Lumineon V, search for whatever piece you may be missing at that time.

Hero's Cape
Make magma snail real big, hard to kill, very good. Alternatively could use Maximum Belt, I tried it and didn't prefer it since 280 was generally enough for a KO in my matchups but it is a solid option if you're going against >280 HP pokes.

Boss's Orders
Wins games

Arven
Search out any item as well as Forest Seal Stone or Hero's Cape depending on which you need/want currently. Keep in mind that Arven can also search Forest Seal Stone as an item, giving you the ability to search both Forest Seal Stone AND Hero's Cape off of a single Arven if need be.

Team Star Grunt
Extra option for guaranteeing a ground burn proc as well as disruption for your opponent's active pokemon's costs as the energy will be discarded.

Ciphermaniac's Codebreaking
Allows you to selectively stack energy for ground burn procs. For extra points, stack another Ciphermaniac's Codebreaking as the second card and go off next turn too!

NOTE: All supporters are searchable by Lumineon V, search whichever one fits whatever you need at the time or experiment with other supporters.
