Gnarled Effigy⁣ - Shadowmoor⁣ (Uncommon)⁣ [251]

Gnarled Effigy is a four-mana artifact that you can tap and pay another four mana to put a -1/-1 counter on any target creature. This means you can gradually weaken your opponent’s creatures while keeping the Effigy around for future use, which is particularly helpful against creatures that rely on their power and toughness to be effective. However, the high mana cost and the fact that you need to spend eight mana to use its ability can make it slow and less effective in fast-paced games, especially if your opponent has ways to remove the Effigy before you can fully utilise its potential.
