Wintermoor Commander

The toughness clause is doing something quietly recursive: this is a Knight whose durability scales with the board it captains, hardening as the tribe swells and thinning to a 2/1 when it stands alone (it counts itself, so it never falls to a zero-toughness body). Deathtouch is the constant that keeps it from ever being irrelevant in combat, trading up no matter how low the headcount runs, so the variable toughness never strands it as a wall that cannot bite. The attack trigger is where the intent as a tribal payoff shows through. Handing indestructible to another Knight for the turn turns your best attacker into a threat blockers cannot profitably trade with, and it can shield a key piece through your own destruction effects: the wrinkle worth sequencing around is a post-combat sweeper of your own, since the granted indestructible outlasts a "destroy" clause cast after the attack step resolves. Against an opponent's board wipe the timing rarely lines up, most sweepers being sorcery-speed and out of reach of a defensive swing, but a self-inflicted Wrath after a favorable attack is a real line. What holds the card together is that its payoffs converge on one axis: the toughness grows with the tribe, the attack trigger needs a Knight beside it to protect, and deathtouch guarantees the body stays a live threat while the count builds. It is a lord that rewards playing the deck it wants rather than printing a flat bonus, and the two-mana cost puts that engine online early.
