Ashes of Outland Cards List & Guide
I've done stuff at rank floor like make a specific counter deck to the most popular meta deck and concede against everything but that deck. (The opponents' rank doesn't matter).
I remember doing this in wild to counter pirate warrior. Had a deck with 8 weapon removals. Was like 95% win against pirate warrior.
