Unlike my hidden gem list, I ignore popularity for this list
Besides coming with a special Disney 100 frame, each card has a satin holographic foil finish
You use the attack and flip two heads out of four, which deals 100 damage and loses you two fire energies, meaning you probably defeated an important mon and still have enough energy to knock out another mon next turn
Sure, you need to play creatures that enter and gain counters (through themselves, or other means), but this team-up will do a lot of extra damage
I have further assumed a distribution of 2 slots to artifacts and colorless cards, 2 each for the five colors, 2 gold cards and either a land slot or an extra gold or artifact/colorless card
The monarch draws a card at the beginning of their end step, and players who aren't the monarch can become the monarch by dealing combat damage to the current monarch or by playing their own monarch card
