A-Circle of the Land Druid

Not yet bracketed (or genuinely unplaceable).

—

2cmc 2/1 Gnome Druid with two triggered abilities: ETB mills 4 (optional self-mill enabler), and on death returns a land from graveyard to hand. Signature in self-mill and graveyard-matters shells where milling fuels payoffs, and in lands-matter where recovering a land on death provides incremental value. The land recursion is death-trigger only, making it vulnerable to exile removal blanking the payoff.
