Realized the Counter to Umbreon is it's pre-evolution, Boosted Evolution Eevee. It can evolve into Flareon before Umbreon can attack. Otherwise use SOE Eevee Once you have 2 Energies on Flareon, it can help do 100 damage per turn: Invest Zone Energy into Aura Zard (30 damage), Attack with Flareon (40 Damage), then Give the additional energy to Zard again (30 Damage). Total of 100 Damage in 1 Turn... AND... The Charizard is all set up to attack once the Flareon gets knocked out.

Everyone’s choosing Entei for draw power but I actually think Fuecoco might be the way to go. It’s faster and more aggressive while not needing 4 energy to still deal 120dmg on turn 2. Then just setting up both zards in the BG to come in and finish. This is faster and I think will output and out dmg entei overall. Like every deck it can brick but it’s been highly consistent in tests.

PKMN_Sensei’s latest update to the reinvented way of playing Mega Rayquaza! With the energy generation support of Ho-Oh EX, Entei EX’s draw power and Fire Type’s ability to generate fast energy, Rayquaza rises from the ashes into power as it was always intended! Switched out A2b Charmander for A1 Charmander to KO baby PKMN. Switched out Lucky Ice Pop & Magby for Flame Aura Charizard & Blue’s Provocation, giving the deck new damage thresholds and control over who Mega Ray K.O.’s.
