Boom BoxHow it works & interactions with other cards

What It Does

Boom Box is a targeted removal engine that can hit three different permanent types: artifacts, creatures, and lands. By paying six mana and sacrificing the Box, you can potentially clear three different cards off the table with a single activation. Because the text says 'up to one,' you have total control over how many things you target.

How It Resolves Step by Step

First, you must pay the six generic mana and tap Boom Box. As part of the cost, you sacrifice the artifact, meaning it goes to the graveyard before the ability even goes on the stack. Next, you choose your targets: one artifact, one creature, and one land. When the ability resolves, all legal targets are destroyed simultaneously. If a target becomes illegal before resolution (for example, if it gains Hexproof), the remaining legal targets are still destroyed.

Common Mistakes

The most common error is assuming you must choose all three targets. You are legally allowed to choose zero, one, two, or three targets. However, you cannot choose two artifacts or two creatures; each target must correspond to one of the three specific types listed. Also, remember that since sacrificing the Box is a cost, your opponent cannot respond by destroying it to stop the ability.

When to Play It

This is a late-game utility piece. It is best utilized when you have an excess of mana and need to break a parity situation. It is particularly effective against 'Tron' lands or powerful utility lands that usually hide safely behind a creature line. Since it is an artifact itself, it fits easily into any deck color identity.

Interaction examples

Multi-Target Removal

Sol RingArcane Signet

If your opponent has a Sol Ring and an Arcane Signet, you might be tempted to hit both. However, since they are both artifacts, Boom Box can only target one of them. You would select the Sol Ring as the 'target artifact,' and if they have no creatures or lands you wish to hit, you simply choose zero for those categories.

Clearing the Path

In a solo scenario, you can activate Boom Box to target a pesky blocker (creature) and a problematic utility land like a Reliquary Tower. Even though you aren't targeting an artifact, the ability is perfectly legal because you are choosing 'up to one' for each category.
