Battlefield Scavenger

In Commander, Battlefield Scavenger slots cleanly into any go-wide or attack-heavy deck that wants to churn through its library without spending mana — think Goblin, Elf, or token strategies where you're swinging with multiple creatures every turn. The effect stacks, so a full board turns a single combat step into several draw-and-discard triggers. In competitive non-rotating formats like Legacy and Modern it's too slow and incidental to earn a slot over dedicated draw engines, but in casual Commander it punches well above its cost. Pioneer players in creature-heavy midrange shells might find it serviceable as a redundant looter, though it faces stiff competition there.
