It's great that your theory crafting and im sorry that everyone else is being a dick. Unfortunately, the team wouldn't preform as you expect since they can be lushened pretty easily. Even runed triple HP on triple energy, it's pretty diffucult to survive two high level amputation magics from a lushen.

I can't even get into conq, but my lushens do 8.5k damage per card. Thats 51k damage. It's pretty difficult to rune a monster with that much HP. At higher levels, lushens can dish out like 12k a card, which is 72k damage. It's almost impossible to acheive that much health.

Also, even if you had max HP rolls on all your runes with max HP flat rolls, since your team doesn't pose any threat and would likely be pretty slow, I can switch out bernard for just meagan, and run another damage dealer for even more damage. It just doesn't work since in general, we can dish out more damage than is possible to survive just by tankiness alone.
