Ill list a number of different ways you can incorporate the graveyard into your builds, regardless of the color(s) or strategy
44,800 Mega Dragonite ex SIR ($287) 42,800 Pikachu ex SIR ($274) 39,800 Team Rocket's Mewtwo ex SIR ($255) 20,800 N's Zoroark ex SIR ($133) 17,800 Marnie's Grimmsnarl ex SIR ($114) 15,800 Iono's Bellibolt ex SIR ($101) 14,800 Canari SIR ($95) 9,480 Steven's Metagross ex SIR ($61) 8,980 Iris's Fighting Spirit SIR ($58) 6,480 Mega Froslass ex SIR ($42) 5,980 Mega Diancie ex SIR ($38) 5,980 Fezandipiti ex SIR ($38) 4,980 Mega Hawlucha ex SIR ($32) 3,780 Mega Eelektross ex SIR ($24) 3,480 Mega Scrafty ex SIR ($22) 1,180 Surfer SIR ($8) As expected, Surfer is the least wanted SIR because he's not a notable character from the games nor a powerful card
Mewtwo remains a top-tier favorite across generations
