Will of the Sultai
The commander check does something unusual for a modal spell: rather than pricing the second mode as a cost, it hands both halves to you for free the moment a commander is on the table, which where commanders are in play is nearly always. Cast blind off a stray turn and you commit to one line: either a recursion effect that mills a target and returns every land from your yard to the battlefield tapped, or a lands-matter pump that scales +1/+1 counters to your land count and staples on trample so the swing lands. Fold the modes together and the sequencing does the heavy lifting: rebuild your board out of the graveyard, then immediately convert that swollen land count into a lethal trampler in a single cast. Each half is reasonable in isolation; the both-choose permission is what tips it toward a blowout, treating a controlled commander as a green light instead of a tax. The color pie underneath is pure green: mass land recursion is green's domain, the sort of effect Splendid Reclamation trades in, and the counter-per-land payoff cares about nothing except how much land you can put into play, with the mill riding along as a cheap way to seed a target's graveyard. Strip the commander away and it collapses to a one-mode sorcery, which is the whole design: a green payoff written to reward decks that almost always satisfy its condition.
