Whenever one or more other permanents phase out and whenever one or more other cards are put into exile from anywhere, put a time counter on The War Doctor.
Whenever The War Doctor attacks, it deals damage equal to the number of time counters on it to any target. If a creature dealt damage this way would die this turn, exile it instead.
The War Doctor is a counters-as-damage attacker: you stockpile time counters by repeatedly phasing permanents out and exiling cards, then swing to fire off a growing burst that snipes creatures, planeswalkers, or faces. Early turns are spent building a phase/exile engine and protecting the Doctor, mid-game you exile from everywhere to balloon the counter, and you close by attacking for lethal direct damage. As a Doctor, he wants a Doctor's Companion in the command zone for added value and resilience.
Add fast mana (Sol Ring, Arcane Signet, Fellwar Stone) and protection (Swiftfoot Boots, Lightning Greaves, Teferi's Protection) so the Doctor reliably survives to attack. Layer in repeatable exile/blink engines—Conjurer's Closet, Restoration Angel, Soulherder via partner companions—and graveyard-hate stax like Leyline of the Void to passively stack counters. Top end with damage doublers (Fiery Emancipation, City on Fire) and Embercleave/Sunforger to convert a modest counter total into a one-shot kill.
