Rosemane Centaur

Convoke and vigilance pull in opposite tactical directions, and that tension is the whole design here. Convoke wants a wide board to discount the cast, tapping your creatures down as payment; vigilance then asks that the resulting 4/4 attack without leaving you exposed. A green-white deck that has spent its early turns flooding the board can drop this ahead of curve by tapping spare bodies, swing for four, and keep the attacker back on defense, papering over the tempo loss that convoke creatures usually suffer once they've cashed in their support. The 4/4 frame is the careful part: big enough to matter in combat and to justify the attack-and-defend split that vigilance offers, but not so large that the convoke discount becomes free value. It is built for the curve-out, not the topdeck, since the mana break only materializes when the board is already developed. As a payoff for go-wide green-white midrange, it does exactly what that archetype wants: it rewards committing creatures early, then converts their presence into a discount on a threat that can swing and still stay home to block.
