Shooting Star — Whenever Auron attacks, put a +1/+1 counter on it. When you do, exile target creature defending player controls with power less than Auron's power until Auron leaves the battlefield.
Auron is a mono-white Voltron beater that snowballs +1/+1 counters every time it attacks while exiling the defender's best blockers along the way. Suit it up with equipment, auras, and counter synergies to push its power high enough that the Shooting Star trigger clears almost any creature, then connect for lethal commander damage. Each attack makes Auron bigger and removes an obstacle, so the board gets safer for you as the game goes.
Built-in repeatable, conditional creature removal that exiles rather than destroys, dodging most recursion
Snowballs power each combat, so Shooting Star quickly threatens to exile nearly any blocker
Vigilance means it attacks and still defends, great for a Voltron commander
Mono-white gives access to the best protection, equipment, and counter support in the format
Commander damage clock closes games fast once it gets going
Heavily reliant on the commander; removal-light tables can still answer it, and it must attack to grow
Mono-white struggles with raw card advantage and ramp compared to other colors
Exile effect only hits creatures with power LESS than Auron, so big blockers can wall it early
Spot removal or 'edict'/sacrifice effects undo your investment and free the exiled creatures
Vulnerable to fogs, damage prevention, and indestructible/protection blockers
