The Incarnations are a cycle that pay you twice: a fair creature when cast, and a static graveyard effect when they die. This is the green one, and its dead-side reward is the most quietly powerful in the cycle, because trample is not a creature keyword the way menace or flying is: it is a damage-routing rule that turns every blocker into a speed bump. Granting it to your whole board from the graveyard means the moment the 3/3 dies and you control a Forest, every fatty you cast afterward stops getting chump-blocked. The design tension is in the requirement: it has to reach the graveyard first, which makes it a creature you are happy to cast into a trade or feed to a sacrifice outlet, and the Forest clause keeps the static ability honestly green rather than a free splash for any deck running a reanimation package. There is a self-contained synergy in the build, too. Cast it, let it die, and now anything you reanimate (including, if you have a way to do it, the rest of the cycle) comes back swinging with trample. It is one of the cleanest expressions of green's "your creatures connect" identity: not a pump spell, not a one-time trick, but a permanent reroute of combat math that lives in the place most cards stop mattering.
