Expanded List of Basics for Marshadow GX

[Mw2020]

I need a list of good basic pokemon to pair with Marshadow GX, besides nightmarch and Drampa GX and Tauros GX. Expanded format.

I've been testing Marshadow GX for Standard so I'm assuming you'll at least find this list slightly useful, hopefully.

"Must-have"
Jirachi XYP (Stardust)
Tapu Lele GX
(Tauros GX)
(Drampa GX)
Zygarde-EX (in Expanded probably Lucario-EX)
Seismitoad-EX
Mewtwo-EX (X-Ball [superior to Lele because it hits weakness])
Kyurem-EX/Zekrom/Reshiram (Outrage)

Useful/Helpful
Shaymin-EX ROS (Sky Return can come in handy)
Oricorio (shreds Night March and Vespi/Flareon)
Lugia-EX (Deep Hurricane)
Pidgeot-EX (not so much in Expanded as most things will one shot you regardless)

Not sure if you're still looking for input on this but I've been running a Standard variant on PTCGO to great success. For both Standard and Expanded you'll want Jolteon EX and Glaceon EX. Being able to shut down basics and evolutions respectively is huge and they are essentially the core of the deck. In Expanded you can also throw in a single Regice (forgot which set, but it's the one that has an attack that prevents damage from EX Pokémon). I personally run a Clefairy EVO in my Standard variant and would run it in Expanded as well. Being able to copy the opponent's active's attack has proven pretty useful. Espeon EX is great for devolving all your opponent's Pokémon and has an attack that ignores all effects. Flying Flip promo Koko is good for spread damage and softening up the bench, and Necrozma GX's GX attack is even better at softening up a bench full of GX and EX Pokémon.

I've also seen some Expanded lists run a single copy of Latios EX for the donk potential turn 1. Personally I don't run Jirachi XY67 in my Standard list anymore. It's used solely for decks running special energy, and Drampa GX has Righteous Edge which discards special energies, while also having 2 other relevant attacks. Granted, Drampa GX doesn't give protection like Jirachi, but against decks without special energy Jirachi is a dead card whereas Drampa GX (and Tauros GX) are always 2 of your biggest damage enablers.

For reference, my Pokemon list for Standard is:
4 Marshadow GX
2 Jolteon EX
2 Glaceon EX
1 Espeon EX
1 Drampa GX
1 Tauros GX
1 Tapu Koko SM31
1 Clefairy EVO
1 Necrozma GX
1 Oranguru
2 Tapu Lele GX
1 Litwick STS (Attack lets you put 2 cards from library into discard for 1 energy. Unnecessary in Expanded because of Battle Compressor)

For Expanded I would drop Litwick and probably Oranguru for Seismitoad EX and Oricorio. Probably find room for a Lugia EX as well and maybe Hoopa EX to put 3 EX Pokémon in hand to discard with a Sycamore. Oranguru just ensures you can always use Ultra Ball/Plumeria/Sophocles even when in top deck mode/N'd late game, but with Battle Compressor all but the Ultra Balls would likely be dropped anyway.

tl;dr - Jolteon EX and Glaceon EX

 

[Dark Espeon]

Consider Marshadow GX in Rainbow Road as the fifth Xerneas.

 

[joffreyspikes]

Drampa, Tauros, Seismitoad, Toxicroak, Jolteon, Glaceon, Dad/Necrozma, Oranguru. Clefairy, Mewtwo, Lucario and Landorus are the obvious ones for me.

I really like mimikyu with marshadow. Especially if you're already using psychic energy from the nercozma/espeonEX combo.
