[Expanded] Jolteon-GX

How this deck can be played to be... somewhat invincible

This deck features Jolteon GX. I'm sure there are a lot better attackers, but this one is kind of invincible if you use it in the right way.

All you have to do is have Vaporeon (Ancient Origins) in play, so Jolteon will become water type, then play Misty & Lorelei (Cosmic Eclipse) so Jolteon can use it's GX attack endlessly, because it is now lightning and water type, because of Vaporeon's ability, and Jolteon GX's attack has the secondary effect of being, well, invincible for the next turn.

So, you can just be invincible, but anyone can still use Boss' Orders, Escape Rope, Guzma, or whatever to swap your pokemon out, so the idea is still a work in progress.

Other Helpful Pokemon

This deck also has Dedenne-GX (Unbroken Bonds) . You won't really be able to use it's GX attack, but it's helpful ability and can paralyze your opponent is pretty helpful, and it will also be searchable off of Electromagnetic Radar (Unbroken Bonds) which is mentioned later. It also has Mew (Unbroken Bonds) as bench protection. Exeggcute (Plasma Freeze) can help you with the discarding effects of Ultra Ball (Scarlet & Violet) ,  Electromagnetic Radar, and Misty and Lorelei. You can take it back to your hand as much as you need during your turn if it is in your discard pile.

Helpful Trainer Cards

VS Seeker (Phantom Forces)is helpful for when you need to take supporter cards out of your discard pile. Some other helpful supporter cards are Marnie (Sword & Shield) , Iono (Paldea Evolved) , Pokémon Fan Club (Fates Collide)  and even Misty and Lorelei if you need it for some reason.

Battle VIP Pass (Fusion Strike) is helpful for getting quick basic pokemon, Nest Ball (Scarlet & Violet) is pretty similar, and Lost Vacuum (Crown Zenith) can get rid of your opponent's stadiums or tools, so you can slowly get rid of their stadium amount so you can play Thunder Mountain ◇ (Lost Thunder) which is helpful to lower Jolteon GX's attack cost, but unfortunately you can only have one in your deck.

Thank you for taking your time to read this long description.

Feedback would be appreciated, enjoy!
