Xyru SpecterHow it works & interactions with other cards

The Price of a Challenge

When Xyru Specter deals damage to an opponent, its triggered ability goes on the stack. The damaged player faces a choice: discard one card immediately or 'challenge' you. If they challenge you, you have the opportunity to reveal cards from your hand. If you can show them two black cards, the penalty for their curiosity is severe, forcing them to discard two cards instead of one. If you cannot or choose not to show the cards, no cards are discarded.

Resolving the Trigger Step-by-Step

First, Xyru Specter must deal damage (usually combat damage) to an opponent. Second, the ability triggers and the opponent decides whether to challenge. Third, if a challenge is issued, you may reveal any number of cards from your hand. If the revealed set contains at least two black cards, the 'if challenged' condition is met with success. Finally, the opponent discards the appropriate number of cards based on the outcome.

Common Mistakes and Rulings

A common point of confusion is what happens if you are challenged but have fewer than two black cards. In this scenario, the opponent discards nothing. You are never forced to reveal your hand; you only reveal if you wish to prove you have the black cards. Additionally, note that while the printed card says 'Summon — Specter,' modern rules treat Xyru Specter simply as a Creature — Specter.

When to Attack

Xyru Specter is most effective when your hand size is large, making the threat of having two black cards believable. It excels in mono-black or heavy-black decks where you are statistically likely to win any challenge. Use its flying evasion to bypass blockers and consistently pressure your opponent's card advantage.

Interaction examples

Replenishing Your Hand

Solemn Simulacrum

To make a challenge more dangerous for your opponent, you need cards in hand. After Solemn Simulacrum dies and allows you to draw a card, you may draw into the second black card needed to win a challenge. When Xyru Specter later deals damage, your opponent must weigh the risk that the card you just drew provides the ammunition to force a two-card discard.

The Strategic Sacrifice

Commander's Sphere

If Xyru Specter's ability triggers while you only have one black card in hand, you can respond to the trigger by sacrificing Commander's Sphere to draw a card. If that new card is also black, you now have the two cards necessary to win a challenge. This instant-speed draw can bait an opponent into a challenge they thought was safe.
