Black mana

[GerKingOfKings]

Hey guys. A friend of mine got a black creature, i think vampire or zombie but im not shure, who can make one black mana for every swamp you control. If one of you know this creature, please post its name. Thanks ahead, king

Easy. Go to advanced filter, select searching by Text only, highlight Black, switch both Match colours and Exclude unselected to on, select Creature type, search for 'for each Swamp' and Bob's your uncle.
