Null Elemental BlastHow it works & interactions with other cards

A Multicolored Menace

Null Elemental Blast specifically targets multicolored objects. An object is multicolored if it has two or more colors in its color indicator or mana cost. If a spell or permanent is colorless or only one color, this spell cannot target it. Unlike its 'Blast' predecessors, it requires a colorless mana, produced by sources like Wastes or Eldrazi Scions.

Step-by-Step Resolution

First, you choose which mode to use as you cast the spell: countering a spell on the stack or destroying a permanent on the battlefield. You then choose a legal multicolored target. Upon resolution, the game checks if the target is still multicolored. If the target has lost colors and become monocolored or colorless before the spell resolves, Null Elemental Blast will fail to resolve and have no effect.

Common Pitfalls

A frequent mistake is trying to target a colorless Eldrazi or an artifact that has no color identity. Remember that even if a card requires different types of mana, it is only multicolored if it has multiple colors. Additionally, giving a creature protection from colorless will make it an illegal target for this spell, even if that creature is multicolored.

When to Cast It

This spell is best saved for high-impact gold cards that stabilize your opponent's board. Because it is an instant, you can use the first mode to win a counter-war against a multicolored spell or use the second mode at the end of an opponent's turn to clear a blocker.

Interaction examples

Protecting Your Assets

Eldritch Immunity

If your opponent targets your multicolored creature with Null Elemental Blast, you can cast Eldritch Immunity. By giving your creature protection from each color, it doesn't stop the colorless Blast directly; however, if you use the Overload cost or if the spell was colored, it would fail. Note that since Null Elemental Blast is colorless, protection from all colors does not prevent it from targeting your creature unless the protection specifically includes colorless.

Mana Generation and Timing

Warping Wail

If you lack the colorless mana to cast Null Elemental Blast, you can cast Warping Wail to create a 1/1 Eldrazi Scion token. You can then sacrifice that token to add one colorless mana, providing the exact resource needed to cast Null Elemental Blast and destroy a multicolored threat.
