double fighter booster box Masters This booster pack introduces legendary characters and Mobile Suits from Gundam X Digimon TCG: Double Diamond Booster

Blocks good

Once resolved with some spare blue mana you are likely never get shot of it and are consequently now in a race

Being able to re use that card in your Graveyard that you set up last turn is just phenomenal

The supply is strictly limited (every pack opened is one fewer that exists), and demand from both collectors and investors remains robust

Honorable Mentions I also want to give an honorable mention to cards that exile opposing creatures when they die like Misery's Shadow and Nemata, Primeval Warden

The Crimson King deck can't function without their Resonators, making the search vital to the strategy
