Needletooth PackHow it works & interactions with other cards

Understanding the Morbid Trigger

The Morbid ability on Needletooth Pack is an 'intervening if' clause. This means the game checks twice: once at the exact moment your end step begins to see if a creature died, and again when the ability tries to resolve. If no creature died earlier in the turn, the ability never triggers, and you won't even get a chance to pick a target.

Step-by-Step Resolution

First, the turn must reach the beginning of your end step. Second, the game engine checks the 'Morbid' condition; if a creature (yours or an opponent's) died, the ability goes on the stack and you choose a target creature you control. Finally, if that target is still legal when the ability resolves, you place two +1/+1 counters on it. If the target is removed in response, the ability fails and no counters are placed.

Common Mistakes to Avoid

A common error is trying to kill a creature during the end step to trigger the Pack. Because the check happens right as the end step starts, the creature must have died during the Main Phases or Combat. Furthermore, 'creature' refers only to permanents on the battlefield; discarding a creature card or having one countered does not satisfy the Morbid condition.

Maximum Efficiency

Since Needletooth Pack can target itself, it can quickly become an unstoppable threat. It also counts any creature dying, including tokens. Using sacrifice outlets or aggressive attacks to ensure a death occurs before your end step is the key to mastering this card.

Interaction examples

Cycling for Value

Solemn Simulacrum

If you attack with Solemn Simulacrum and it is blocked and destroyed, its 'dies' ability triggers to draw you a card. Later, when you move to your end step, Needletooth Pack detects that the Simulacrum died this turn. You can then put two +1/+1 counters on the Pack itself or another creature you control.

Doubling Down on Dinosaurs

Roaming Throne

With Roaming Throne on the battlefield naming 'Dinosaur', Needletooth Pack's Morbid ability becomes even more dangerous. If a creature died this turn, the Pack's ability triggers. Because of Roaming Throne, it triggers an additional time. This allows you to put a total of four +1/+1 counters on your creatures—either all on one target or split between two different targets.
