Carte Magic Soul Spike

Soul Spike 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.

01

Official card text

You may exile two black cards from your hand rather than pay this spell's mana cost. Soul Spike deals 4 damage to any target and you gain 4 life.

Complete guide

Soul Spike is a powerful black instant that offers a devastating swing in life totals. It is famous for its alternative casting cost, allowing you to bypass its high mana requirement by exiling cards from your hand. This versatility makes it a staple in aggressive and combo decks that need to finish off an opponent or stabilize their own life.

What Soul Spike Does

At its core, Soul Spike is a 'drain' spell that deals 4 damage to any target and grants you 4 life. While its mana cost is 7 total, you can cast it for free by exiling two black cards from your hand. This alternative cost is paid at the same time you would pay mana, providing a surprise factor that few opponents expect when you are tapped out.

Step-by-Step Resolution

First, you announce Soul Spike and choose its target. Next, you choose whether to pay {5}{B}{B} or exile two black cards from your hand; note that you cannot exile Soul Spike to pay for its own cost as it is on the stack during this step. Once costs are paid, the spell waits for priority to pass. Upon resolution, it deals 4 damage to the target. If the target is still legal, you then gain 4 life. If the target becomes illegal before resolution, the entire spell fails and you gain no life.

Common Mistakes

Players often forget that the alternative cost still counts as casting the spell. Even if you pay zero mana, the spell's mana value remains 7. This is crucial when interacting with effects that care about mana value. Additionally, you cannot use one of the two black cards you are exiling to pay for other costs; they are consumed specifically for the alternative cost requirement.

When to Play It

Soul Spike is best utilized as a finisher or a defensive tool when you have an abundance of black cards. Because it targets 'any target,' it can remove a problematic creature or planeswalker while keeping you alive. In high-stakes matches, it serves as a 'free' way to punish an opponent who thinks they are safe because your lands are tapped.

Interaction examples

High Mana Value Interactions

If an opponent targets your creature with Soul Spike, its mana value is 7 regardless of whether they paid mana or exiled cards. This satisfies the conditions for Not of This World, potentially allowing your opponent to counter Soul Spike for free if your creature has power 7 or greater.

Mana Value in Multi-Target Scenarios

Both Soul Spike and Curtains' Call have high mana values (7 and 6 respectively). If you are playing a format where mana value matters, such as having a triggered ability that checks for spells with mana value 5 or greater, casting Soul Spike for its alternative cost will still trigger that ability, just as Curtains' Call would even if its cost was reduced by the Undaunted mechanic.
