Carte Magic Thriving Moor

Thriving Moor is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

01

Official card text

This land enters tapped. As it enters, choose a color other than black. {T}: Add {B} or one mana of the chosen color.

Complete guide

Thriving Moor is a versatile land that provides black mana while adapting to the needs of your multi-colored deck. It is part of the Thriving land cycle, designed to fix your mana base by allowing you to choose a secondary color upon its arrival. This card is particularly effective in formats like Limited or Commander where consistent access to multiple colors is vital.

Choosing Your Color

Thriving Moor has a replacement effect that happens as it enters the battlefield. You must choose a color—white, blue, red, or green—at the moment it enters. This is not a triggered ability, so players cannot respond to the choice itself. Once chosen, Thriving Moor will permanently be able to produce either black mana or mana of the chosen color for as long as it remains on the battlefield.

Tapped Entrance and Mana Production

The land always enters the battlefield tapped, meaning you cannot use it the turn you play it unless you have an effect that untaps it. When you tap it for mana, you choose between Black or the color you selected when it entered. Even if an effect causes Thriving Moor to lose its abilities, the chosen color is remembered, though it would need those abilities back to actually produce that mana.

Common Mistakes

One common error is trying to choose Black as the second color; the card explicitly states you must choose a color other than black. Additionally, remember that the choice is made as it enters. If you put Thriving Moor onto the battlefield without playing it (such as with a ramp spell), you still make the choice. If the land is flickered or leaves and re-enters, you may choose a different color for its new instance.

Interaction examples

Establishing a Mana Base

If you play Thriving Moor and choose White, you now have access to Black and White mana. If you then play Command Tower in a Mardu Commander deck, you have flexible options. Thriving Moor ensures you can hit your specific color requirements early, while Command Tower scales with your deck's identity.

Mirroring Opponents

If you control Thriving Moor with Red as the chosen color, your Exotic Orchard can now potentially produce Red. This is because Exotic Orchard checks what colors your lands could produce. Since Thriving Moor has an activated ability that could produce {B} or {R}, it adds both to the pool of colors available to your opponent's Exotic Orchard.
