While Invasion of Regatha has some interesting uses, for the most part, there are other cards that do the same thing but better (Stoke the Flames for the front and Solphim, Mayhem Dominus or Urabrask for the back), which puts the battle in C-tier
This is meant to be educational based on my experience
Popular trainers like Blue and Karen have multiple versions featuring them with Eeveelutions like Flareon, Vaporeon, and Umbreon
Fezan is my total chase card but its playable just thinking of Iron Crown thats hella expensive If this card is as expensive as the iron crown Im rioting I want the funny bird #20 but three of those SIRs are from the last set and have been shoved into this one
The reason for this is a bit complicated, though
Browsing through every printed card to find the best combos for your deck can often be a time-consuming process
