Mega Gengar ex Deck Strategy Guide

Lock Out Your Opponent's Trainer Cards

Labyrinth of Shadows can lock opponents out of games, denying them of win conditions or setup tools. It can notably stop an opponent from playing cards like Rare Candy and Cyrus, stopping an opponent from progressing their board states completely.

Use Chingling While You Set Up

Chingling can disrupt an opponent's setup and does not need any Energy to attack. Start with Chingling, and use Jingly Noise as you set up Mega Gengar ex on your Bench.

How to Beat Mega Gengar ex Decks

Set Up Faster than Mega Gengar ex

Mega Gengar ex's attack is very difficult to set up, so prioritize setting up before it is able to use Labyrinth of Shadows. KO as many of its teammates as you can, and have an attacker set up that can take on Mega Gengar ex in a late-game duel.
