Ward—Pay 3 life.
Whenever you gain life, Amalia Benavides Aguirre explores. Then destroy all other creatures if its power is exactly 20. (To have this creature explore, reveal the top card of your library. Put that card into your hand if it's a land. Otherwise, put a +1/+1 counter on this creature, then put the card back or put it into your graveyard.)
Amalia is a lifegain value engine that doubles as a two-card combo deck. Build a BW lifegain shell that drips incremental value, then assemble Amalia + Wildgrowth Walker (plus any repeatable lifegain) to loop explores: Walker gains 3 life when a creature explores, that lifegain triggers Amalia to explore again, and the chain only stops when Amalia hits exactly power 20 and wipes every other creature on board. You're left with a 20/20 ward-protected commander on an empty battlefield ready to swing.
Add tutors that find Wildgrowth Walker or backup lifegain—Diabolic Intent, Demonic Tutor, and Eladamri's Call—plus protection like Heroic Intervention and Teferi's Protection to insulate the combo. Lean harder on cheap repeatable lifegain (Soul Warden, Essence Warden, Heliod) and aristocrat drains (Blood Artist, Zulaport Cutthroat) so the loop is guaranteed lethal rather than just a board wipe. Round out with fast mana and efficient interaction (Swords to Plowshares, Fellwar Stone, Arcane Signet) to combo off ahead of the table.
