How to Beat This Deck

Target Mega Gengar ex

Since losing Mega Gengar ex is an instant loss, focus all your offensive pressure on it. Knocking it out secures you the win.

Prevent Evolution

If possible, disrupt the evolution line before Mega Gengar ex can hit the field. Removing Gastly or Haunter can slow down the deck significantly.
