If another source you control would deal noncombat damage to a permanent or player, it deals that much damage plus 1 to that permanent or player instead.
Whenever you cast an instant or sorcery spell, Tor Wauki deals 2 damage to any target.
Tor Wauki turns every burn spell and ping effect into a damage engine: cast cheap instants/sorceries to trigger his free 2-damage ping (which becomes 3 thanks to his own damage-boost), while your pingers and burn spells each deal extra. You grind opponents down with repeatable noncombat damage, gaining life off lifelink, and close with a big burn payoff or a damage-doubling enabler.
Stacks damage replacement with cheap spells for absurd value—every burn spell hits harder
His cast-trigger ping is free repeatable removal/reach that also gains you life via lifelink
Excellent at picking off mana dorks, X/1 utility creatures, and planeswalkers
Rewards a low curve of cantrips and burn that most BR shells already run
Reach + lifelink make him a respectable blocker, not just a glass-cannon
Damage-based plan struggles against fogs, lifegain, and high-life or hexproof opponents
Relies on the commander being out; he's a removal magnet and recasting gets expensive
Limited to two colors with no ramp or card advantage outside that color pair's norms
Burn doesn't scale well against three opponents and 40 life totals without doublers
Vulnerable to graveyard hate if leaning on spell recursion
Combines with any board damage to redirect huge amounts to creature controllers, often lethal.
Lower your curve and add more free or near-free pingers and cantrips so Tor Wauki triggers multiple times per turn; stack damage multipliers like Torbran, Fiery Emancipation, and Solphim, Mayhem Dominus to make each point count for far more. Add fast mana (Jeska's Will, rituals) and a few protective pieces so your commander sticks, then include a combo finish like Heartless Hidetsugu or damage-doubler loops to convert incremental burn into a clean kill.
