Polluted Mire 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.

Official card text

This land enters tapped. : Add . Cycling (, Discard this card: Draw a card.)

Complete guide

Polluted Mire is a versatile black-aligned land that offers utility throughout every stage of a Magic: The Gathering match. Whether you need a mana source to establish your board or a way to refresh your hand late in the game, this card provides essential flexibility for black decks.

What It Does

Polluted Mire serves two primary functions: it is a land that provides black mana and a card that can be cycled away for a new draw. It enters the battlefield tapped, meaning you cannot use its mana on the turn you play it. However, its Cycling ability allows you to pay two generic mana and discard it from your hand to draw a card, which is perfect for avoiding 'mana flood' when you already have enough lands.

How It Resolves Step by Step

When you play Polluted Mire as your land for the turn, its static ability applies, and it enters the battlefield already tapped. Once on the battlefield, you can tap it for one black mana during any turn it is untapped. If you choose to use the Cycling ability, you pay the cost of two mana and discard the card as part of the activation. This goes on the stack as an activated ability; once it resolves, you draw one card from your library.

Common Mistakes

A frequent error is trying to play the land and cycle it at the same time. Cycling can only be activated while the card is in your hand. Once Polluted Mire is on the battlefield, it is a permanent and can no longer be cycled. Additionally, remember that because it enters tapped, it cannot be used to pay for its own cycling cost or any other spells on the turn it is played.

When to Play It

Play Polluted Mire early in the game if you are missing land drops and need to build your mana base, especially if you have an opening in your curve to accommodate a tapped land. In the late game, if you already have a sufficient amount of mana, it is usually better to spend two mana to cycle it in search of a threat or a defensive spell.

Interaction examples

Establishing Mana with Command Tower

Command Tower

On turn one, you play Command Tower and tap it to play a one-mana spell. On turn two, you play Polluted Mire. Because Polluted Mire enters tapped, you cannot use it immediately, but you now have two lands ready for turn three, ensuring you have the black mana required for more complex spells.

Reacting to Opponents with Exotic Orchard

Exotic Orchard

If your opponent controls a land that produces blue mana, your Exotic Orchard can now produce blue. If you find yourself needing a specific blue counterspell rather than another black mana source, you can use the mana from Exotic Orchard and one other land to cycle Polluted Mire, digging deeper into your deck for that specific answer.

Cycling in a Pinch

You have six lands on the battlefield and Polluted Mire in hand. Instead of playing it as a seventh land which you don't currently need, you pay two generic mana and discard it. The cycling ability resolves, and you draw a new card, potentially finding a creature or removal spell to help win the game.
