mtg phyrexia all will be one commander precons Are the Phyrexia: decks worth buying? Then each creature your opponents control gets Phyrexia: All Will Be One

Pets are available for purchase in the MTG Arena Store

They also mostly have harmless effects in play: Greed in the black castle and Sylvan Library in the green (the computer spends all its life and mana drawing too many cards), Leviathan in blue (the computer will laughably strangle itself sacking its islands to that), Elder Land Wurm in white (trades with Juggernaut, fly over it with Hyppie, or just Paralyze it.) The scary one is Mana Flare in the red castle, which plays a little too well with the red decks powering up X damage spells

On TCGPlayer , the Enchanted Yen Sid - Powerful Sorcerer is valued at $295

They arent numbered or counted in the main set and only come as standard cards not foil
