Hapatra, Vizier of PoisonsHow it works & interactions with other cards

Applying Pressure and Poison

Hapatra has two distinct abilities that work in harmony. First, whenever she deals combat damage to a player, you can choose to place a -1/-1 counter on any creature on the battlefield. Second, whenever you put one or more -1/-1 counters on any creature—including Hapatra herself—you create a 1/1 green Snake creature token with deathtouch. This secondary ability triggers for every creature you put counters on, meaning if you weaken multiple foes at once, you get multiple Snakes.

Step-by-Step Resolution

When Hapatra deals combat damage, the triggered ability goes on the stack and you choose a target creature. Once that ability resolves, the counter is placed. Immediately after that counter is placed, Hapatra's second ability triggers because a counter was put on a creature. Finally, that second trigger resolves, and you place a 1/1 Snake token with deathtouch onto the battlefield under your control.

Crucial Interactions to Remember

A common mistake is thinking Hapatra only triggers when she deals damage. In reality, any effect you control that places -1/-1 counters will trigger her token generation. Furthermore, if you place multiple counters on a single creature at once, you only get one Snake. However, if you place counters on two different creatures simultaneously, Hapatra's ability triggers twice, giving you two Snakes.

When to Deploy the Vizier

Hapatra is best played in the early game where her low mana cost allows her to start generating value immediately. She is particularly effective against decks that rely on small utility creatures, as she can pick them off with counters while building a defensive wall of deathtouch Snakes to deter larger attackers.

Interaction examples

Targeting Utility Creatures

Birds of Paradise

If Hapatra deals combat damage to your opponent, you may choose to put a -1/-1 counter on your opponent's Birds of Paradise. Because the Birds of Paradise has 1 toughness, the -1/-1 counter will cause it to be put into the graveyard. Simultaneously, Hapatra's second ability triggers, granting you a 1/1 Snake token.

Cleaning the Board

Llanowar Elves

If you use an outside spell to place a -1/-1 counter on an opponent's Llanowar Elves while Hapatra is on the battlefield, Hapatra's second ability will detect this event. Even though Hapatra didn't deal damage, the act of placing the counter fulfills her requirement, and you will create one 1/1 Snake token with deathtouch.

Self-Sacrifice for the Swarm

Snake

If an effect forces you to put a -1/-1 counter on Hapatra, Vizier of Poisons herself, her ability still triggers. Even if the counter reduces her toughness to 0 and causes her to leave the battlefield, the ability triggered at the moment the counter was placed, ensuring you still receive a 1/1 Snake token.
