Invasion of Lorwyn // Winnowing Forces clears the board of non-Faeries and non-Elves the moment it resolves, then flips into a 4/4 flier that makes more bodies every upkeep. The cost is real — six mana on the back half means you're not winning fast games with this — but the payoff in tribal mirrors is lopsided enough to justify the slot.

Commander is where Invasion of Lorwyn // Winnowing Forces earns its keep, specifically inside Faerie or Elf tribal builds that can protect their own pieces through the wipe and then snowball off Winnowing Forces's token generation over multiple upkeeps. Outside tribal, the asymmetric clause disappears and you're paying five mana for a conditional board wipe with a slow payoff, which is too clunky to compete with dedicated sweepers. In Modern and Pioneer it's fringe at best — the battle mechanic requires too much setup for a format that wants answers on turn two or three. Legacy and Vintage have no interest.

Price Context
Current price
$0.09 bulk tier
At $0.09, Invasion of Lorwyn // Winnowing Forces is deep bulk — no financial barrier to picking up copies. The price reflects narrow tribal demand rather than any power-level ceiling, so it's unlikely to spike unless a competitive Faerie shell emerges.
