Quilled Greatwurm - Magic: The Gathering Foundations (Mythic) [FDN-111]

Quilled Greatwurm is a creature from the Foundations set, costing {4}{G}{G} and featuring trample. It rewards aggressive strategies by adding +1/+1 counters to creatures you control whenever they deal combat damage during your turn, as long as they survive the encounter. This ability can quickly turn your smaller creatures into substantial threats. The option to cast it from your graveyard by removing counters adds another layer of utility, allowing you to recycle your threats if you're able to accumulate enough counters.
