Drag to the Underworld 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 spell costsless to cast, where X is your devotion to black. (Each
in the mana costs of permanents you control counts toward your devotion to black.) Destroy target creature.
Complete guide
Drag to the Underworld is a powerful black removal spell that rewards you for leaning heavily into its color. While its base cost might seem high for an instant, your devotion to black can significantly discount its price, making it a highly efficient answer to threats.
Understanding Devotion and Reductions
Drag to the Underworld features a cost reduction ability based on your devotion to black. To calculate this, count the total number of black mana symbols in the mana costs of all permanents you control on the battlefield. Each symbol reduces the generic mana portion of the spell's cost by {1}. Note that this cannot reduce the colored mana requirement; you must always pay at least {B}{B} to cast this spell.
Casting Step-by-Step
When you cast Drag to the Underworld, you first announce the spell and choose your target creature. Next, you calculate the cost by taking the initial {2}{B}{B} and subtracting {1} for each black mana symbol you control. Once you begin this process, opponents cannot respond by destroying your permanents to increase the cost. You pay the final amount and the spell is officially cast and put onto the stack.
Common Mistakes
A frequent error is trying to count mana symbols in text boxes, like activated ability costs; only symbols in the upper right corner (or the left side for certain layouts) of your permanents count. Additionally, remember that while the cost you pay changes, the mana value of Drag to the Underworld remains 4. This is important for cards that care about the mana value of spells on the stack.
When to Play It
This spell is best utilized in mono-black or heavy-black decks where your devotion is consistently high. Unlike spells with fixed alternative costs, Drag to the Underworld scales with your board state. It is an excellent inclusion when you need reliable, instant-speed interaction that won't strain your mana pool in the mid-to-late game.
Interaction examples
If you control a creature with a mana cost of {B}{B}, your devotion to black is two. When you cast Drag to the Underworld, the cost is reduced by {2}, meaning you only pay {B}{B} to destroy a target creature.
Deadly RollickWhile Deadly Rollick offers a free cast if you control your commander, Drag to the Underworld provides a similar efficiency in non-Commander formats or when your commander isn't present. If your devotion is 2 or more, both spells become highly competitive, though Drag to the Underworld destroys the target while Deadly Rollick exiles it.
Fell the Profane // Fell MireIn a deck using Fell the Profane // Fell Mire, you have flexibility against planeswalkers. However, Drag to the Underworld is often easier to cast for a low mana investment during your opponent's turn if you have an established board of black permanents, allowing you to keep mana open for other plays.
