Nekrataal AvatarHow it works & interactions with other cards

What It Does

Nekrataal Avatar provides a passive reduction to the cost of creature spells you cast. Specifically, it reduces the cost by one black mana ({B}). Unlike most cost-reduction effects that target generic mana, this ability specifically discounts the colored mana portion of a spell's cost.

How it Resolves Step by Step

First, you declare you are casting a creature spell and move it to the stack. Next, you determine the total cost by starting with the mana cost or an alternative cost, adding any cost increases, and then applying cost reductions. Nekrataal Avatar applies its {B} reduction at this stage. Finally, you pay the resulting total cost; if the spell originally required {B}, that requirement is now satisfied.

Common Mistakes

The most common error is attempting to use this reduction on generic mana costs. If a creature costs {2}{G}, Nekrataal Avatar provides no benefit because the spell does not have a {B} component to reduce. Additionally, this effect only applies to the colored mana symbols in the cost, meaning it cannot make a spell cost less than its generic mana requirement if no black mana is present.

When to Play It

This card is most effective in decks featuring high concentrations of black creatures, especially those with many black mana symbols in their costs (such as 'Devotion' strategies). It allows you to curve out faster than your opponents by effectively providing a free mana source that is always active on your side of the board.

Interaction examples

Casting with Basic Lands

Command Tower

If you have Command Tower and tap it for black mana to cast a creature that costs {B}{B}, Nekrataal Avatar reduces the cost by {B}. You only need to spend the one black mana from Command Tower to successfully cast the creature.

Interacting with Colorless Sources

Sol Ring

When casting a creature that costs {2}{B}, you can use Sol Ring to pay the {2} generic mana. Nekrataal Avatar then reduces the remaining {B} cost to zero. This allows you to cast a three-mana creature using only a Sol Ring and the Avatar's passive ability.
