Champion of the Arena thread

[amyndris]

Any advice on how to no loss the Arena Grand Champion? I've tried solo plants with Hagrid but he seems to murder them faster than Hagrids rebuff.

I've tried a lineup of Red Dragon/Paladin/Inquisitor/Repair Droid/Guard Droid, but their DPS isn't fast enough to down him before his "spawn enemy" attack grows too much for me to take down in a single turn, even with Level 3 Demon Slayer can't do plants because he murders them too fast.

I'm Mage/Impossible. Thanks for any help you can give me! I've managed to no loss my way here, but now I'm stuck :/
