Overwhelming Stampede - Commander: Marvel Super Heroes (Rare) [MSC-178]

Overwhelming Stampede is a five-mana sorcery from Marvel's Spider-Man Commander set that pumps your whole board, granting trample and +X/+X to every creature you control until end of turn, where X equals your biggest creature's power. It scales with the size of your largest threat, so a single huge creature can boost an entire team into lethal territory. This fits mono-green go-wide strategies, especially decks that also run one or two oversized creatures to maximise the bonus. Note that it only lasts until end of turn, so it needs to be cast when you're ready to swing for the win rather than as a defensive tool.
