Monstrous War-Leech enters as a copy of the biggest creature on the battlefield, which means it can land as a 10/10 trampler or a combo piece for essentially nothing — the downside is that your opponent chose what you're copying, not you. Four mana for a potentially massive threat with upside is the deal; the variance in what you get is the tax.

Commander is where Monstrous War-Leech earns its slot — multiplayer tables reliably have a target worth copying, and four mana for a clone that scales to the biggest thing in any of three opponents' boards is genuine value. In one-on-one formats like Legacy or Vintage, the copy effect is narrower and slower, and those formats have better payoffs at the same mana cost. Modern and Pioneer could theoretically support it in a value shell, but the lack of a guaranteed target and the competition from purpose-built threats make it a fringe inclusion at best. Commander remains the clear home.

Price Context
Current price
$0.07 bulk tier
At $0.07, Monstrous War-Leech is deep bulk — you're picking this out of a dollar box or grabbing a playset for the cost of a pack of gum. Bulk rares with narrow applications don't tend to climb unless a Commander deck or combo breakout finds them, and nothing on the horizon points that direction for this one.
