Dot Proxy, Netrunner

A player losing unspent mana causes that player to lose that much life.

Whenever Dot Proxy, Netrunner or another creature you control is turned face up, heist target opponent's library.

During your turn, you may tap lands you don't control for mana. Spend this mana only to cast face-down spells or spells you don't own.

Disguise—Pay {2}. Spend only blue, black, and/or red mana to activate this ability.
