Can't get passed this team - as I said no blocker left and I tried Opera Ed, Gunner Krampus, Warrior Snowman and Sentinel Shinobi - sleep and stun as strategy. Everything fully sharded.
Lost the coin toss and FFE 1 shot the Krampus - long story short - Shinobi made it to the 3rd round and ...
After that I did a small experiment. As I don't play Arena but the fight a day I fell into deeper regions (1400ish) ... so I started fights with only FFE. I lost a few because he got stunned all the time. So I gave him wearing Angel and Power Shield and won 50 % ish. After that I ran FFE and Madam with Oracle and just with those 2 I cleared a full list - 1 team pulled up a bit of a fight but I basically ran through.
So I thought I put those 2 into defense - just those two. Checking a day later I have 8 out of 10 wins in defense. Sure I got quite a few relics but really? Pretty much shows how OP all this new stuff is ... Looking forward to next Arena event that I can run on autoplay I guess ...
