Saskia the Unyielding

The redirected combat damage is the whole strategic engine, and it reframes what your attacks are doing: instead of choosing which opponent to whittle down each turn, every creature that connects taxes two life totals at once. Pick an opponent as Saskia enters and any point of combat damage your board lands on a player gets mirrored onto that chosen one, turning a wide swing into a fork the table cannot all answer at the same time. The trigger keys off damage dealt to a player, so it rewards going wide enough that defenders cannot cover every lane: a creature that gets chump blocked deals no damage to a player and mirrors nothing, but every attacker that slips through hits twice. That makes her a clock that compounds with each unblocked attacker rather than each attack, and it pressures the whole table to defend against everyone, since any opponent's blocks can leave the chosen player exposed. The four-color identity is the cost of admission: she demands one of the most punishing color spreads a deck can field, and a 3/4 with vigilance and haste is built to attack the turn she lands and keep blocking on the swing back. She sits in a lineage of commanders that convert a board into focused-fire reach, but few do it this cleanly: no payment, no tap, no setup. You choose, you attack, and one player starts losing faster than the battlefield math suggests.
