Mega Diancie ex Deck Strategy Guide

Load Up Mega Diancie ex with Energy

Mega Gardevoir ex can set up Mega Diancie ex with Fantasia Parade. Once it has enough Energy to score a KO, it can switch in and start attacking.

Use Non-ex Pokemon Against Pom-Pom Oricorio

Since the deck relies on multiple Mega ex Pokemon, Pom-Pom Oricorio may be a challenging matchup. Make use of non-ex Pokemon like Xerneas to knock it out.

How to Beat Mega Diancie ex Decks

Use Efficient Attackers

While Mega Diancie ex isn't weak to Darkness, Hydreigon is difficult for it because of its low HP and susceptibility to getting KOd.

Missing KOs on this Pokemon can prove costly in this matchup, as it lets the Hydreigon player set up another attacker to finish Mega Diancie ex.
