Lethal Vapors + Pithing Needle

Lethal Vapors

Pithing Needle

How it works

1. Whenever a creature enters the battlefield, Lethal Vapors triggers, destroying that creature.
2. Because Pithing Needle prevents Lethal Vapors's activated ability from being activated, it cannot be destroyed due to its ability.

This clever little lockout relies on Lethal Vapors's dual nature: its triggered ability automatically acts as an iron-clad deterrent by wiping out any creature the moment it enters the battlefield, while its self-destruction ability would normally let someone pay zero mana to skip their next turn and scrap the enchantment. That is precisely where Pithing Needle comes in; by naming Lethal Vapors as it enters, Pithing Needle silences that pesky self-destruct button forever. The result is a permanent, untouchable board state where creatures are doomed the second they arrive, completely locking down anyone who tries to deploy a creature-based strategy.
