Penumbra Bobcat

The whole point is that the death trigger turns a single removal spell into a wash: aim a kill spell at the green 2/1 and you have spent a card to leave its stat-for-stat replacement still standing, now in black. That refusal to give the opponent a clean one-for-one is the entire design, shared with a handful of creatures whose dying is a downpayment rather than a loss. This is the green entry, a 2/1 for that hands back a 2/1 black Cat token when it dies. The color flip is the wrinkle worth noticing: on its own it reads as flavor (the original casting a shadow), but in a deck that cares about creature color, or in a sacrifice shell that wants a second body to feed an outlet, that swing from green to black is doing real positional work. The rate was never the appeal: two 2/1s spread across two turns is a slow, fragile clock, and an opponent who simply blocks profitably or holds a sweeper still comes out ahead. What the design buys is resilience against the cheap targeted removal that defines so much of fair play, splitting one creature's value across two cards' worth of attrition so that the obvious answer never fully answers it.
