MTG: Universes Beyond- Final Fantasy Bundle View product details MTG: Universes Beyond- Final Fantasy Bundle $69.99 This Bundle includes a full inventory of treasures, with 9 Magic: The GatheringFINAL FANTASY Play Boosters (each containing 14 cards), 2 Traditional Foil Extended-Art cards, 16 Traditional Foil and 16 nonfoil Full-Art Basic Land cards, 1 oversized Spindown life counter, 1 FINAL FANTASY card storage box, and 2 reference cards
I only listed the foil prices above because the formats I can see this being most useful are Legacy and Vintage, where Xantid Swarm has been useful out of the sideboard
But these counters also represent Domris toughness, so if your opponent attacks Domri and the card suffers damage, you lose one counter for every point of damage sustained
