pokemon n reshiram card N's - 109/100 (109/100) Japanese Original Edition N's Reshiram Card Art :

Whenever enchanted Forest is tapped for mana, its controller adds one mana of the chosen color to his or her mana pool (in addition to the mana the land produces)

However, nicer cards cost a bit more, with HP jumping to $27, while an MP copy surged to $71

Brood Sliver will give Slivers a combat damage trigger that will let the Sliver's controller create a 1/1 colorless Sliver creature token

This is a card advantage machine

However, when you play more colors, it also becomes more likely that you'll be stuck without the proper colors of mana to play one of your spells, which will lower the consistency (or reliability) of how your deck functions
