Astarion's Thirst puts a -1/-1 counter on a creature and drains an opponent for 1 life — instant speed, two mana, and it triggers Astarion, the Decadent's bite mechanic cleanly. It's not a premium removal spell, but as a cheap, on-theme interaction piece that also advances your life-gain and counter synergies, it earns its slot.
Best Commanders
Commanders with the highest synergy

Astarion, the Decadent
Astarion, the Decadent feeds directly on what Astarion's Thirst does — the drain triggers life-gain payoffs and the -1/-1 counter softens creatures for the commander to finish off or trade through.

Skullbriar, the Walking Grave
Astarion's Thirst puts a -1/-1 counter on an opponent's creature at instant speed, which pairs with the -1/-1 counter synergies that Skullbriar, the Walking Grave shells often build around to grind down the board.

Killian, Ink Duelist
Killian, Ink Duelist reduces the cost of Auras and spells that target creatures, making Astarion's Thirst effectively a one-mana instant-speed drain-and-weaken that slots cleanly into Killian's tempo gameplan.

Sarulf, Realm Eater
Sarulf, Realm Eater scales on -1/-1 counters placed on permanents, and Astarion's Thirst provides a cheap, repeatable way to stack those counters while draining life as a bonus.

Kotis, the Fangkeeper
Kotis, the Fangkeeper rewards life-gain and creature-weakening effects, and Astarion's Thirst delivers both on a single instant-speed card that fits the deck's overall drain-and-survive strategy.

Astarion's Thirst is a Commander-first card — its power is tied to tribal and life-gain synergies that the 100-card singleton format supports far better than any 60-card format. In Legacy and Vintage, where it's technically legal, a two-mana instant that deals 1 damage and places a single -1/-1 counter simply doesn't compete with the raw efficiency of that format's removal suite. Oathbreaker is the other home worth mentioning: commanders that care about life totals or -1/-1 counters can extract real value here. Everywhere else, the card doesn't exist competitively.
