Acidic Dagger costs four mana to equip and forces your opponents to sacrifice lands whenever the equipped creature deals combat damage — a punishing effect that never quite justifies the price tag. Seven mana to suit up is prohibitive in almost every context, and there are faster, cheaper ways to apply land destruction pressure.

Where it lives, where it can’t
| Format | Verdict |

Acidic Dagger is legal in Commander, Legacy, Vintage, and Oathbreaker, but sees essentially no play in any of them. In Commander, the equip cost of four makes it nearly uncastable in a meaningful window — by the time you're spending seven mana total to connect with one creature, opponents have already stabilized. Legacy and Vintage have no interest in a four-mana artifact with a conditional land-destruction rider when faster, more reliable tools exist. Oathbreaker offers the most charitable environment given lower player counts, but even there Acidic Dagger struggles to justify its slot.
