I know of one effective strategy to counter a team like that: have the first turn.
It's really that simple! As long as you go first, you have a chance at winning!
Now, this may sound like an unreasonable thing to attempt, but fear not; I have it on good authority that NF will soon be adding a relic to the store that will grant players the ability to always go first in the arena OR gauntlet at the cost of 150 ironite (or $2.99) per battle, allowing players and the AI to fight on even grounds!
