A creative-refresh system so you never run dry

A creative-refresh system so you never run dry
Trench note: the buyers who never go red are the ones with creatives in the bank. Build the system.

— Every Monday: produce 5 new creatives, win or lose. Non-negotiable cadence.
— Keep a 'morgue' folder of old winners — rotate them back after 30 days, they re-perform.
— Track CTR by creative day over day. The day it drops 20% from peak, the replacement is already queued.
— Vary ONE element per new batch (angle / thumbnail / headline) so you keep learning while you refresh.
— Steal your own winners across GEOs before you ever start from a blank page.

Fatigue is scheduled, not surprising. Plan for it.
Go test it.
