Shadowblood RidgeHow it works & interactions with other cards

What it Does

Shadowblood Ridge is a non-basic land that provides both Black and Red mana. Unlike standard dual lands, it requires an investment: you must pay one generic mana and tap the land to receive two mana ({B}{R}) in return. It cannot produce mana on its own without this payment.

How it Resolves

Activating Shadowblood Ridge is a mana ability, which means it does not use the stack and cannot be responded to. First, you announce the ability. Then, you pay the cost of one mana from another source and tap Shadowblood Ridge. Immediately, one Black mana and one Red mana are added to your mana pool.

Common Mistakes

The most frequent error is forgetting that Shadowblood Ridge cannot produce mana if it is your only land. Because it has a cost of {1}, you must have another source of mana available to 'filter' through it. Additionally, remember that it produces exactly one Black and one Red; you cannot choose to produce two Black or two Red mana.

When to Play it

This land shines in multicolor decks where you have high counts of generic mana but specific color requirements for spells. It is best played alongside lands that produce mana freely, ensuring you always have the {1} required to activate its filtering ability.

Interaction examples

Filtering for Rakdos Spells

Command Tower

With both lands on the battlefield, you can tap Command Tower to produce one mana of any color. You then spend that one mana to pay the cost of Shadowblood Ridge's ability. By tapping Shadowblood Ridge, you now have one Black and one Red mana available to cast a spell.

Using Opponent's Mana Sources

Exotic Orchard

If an opponent controls a Forest, you can tap Exotic Orchard for one Green mana. You use this Green mana to pay the activation cost of Shadowblood Ridge. Even though you started with Green mana, Shadowblood Ridge successfully filters it into {B}{R}.
