I was thinking about this hypothetical question at work today (not sure why), and I thought it might be interesting to pose this question to the community and see what other people think.
Assume that you have access to as many as you want of any maxed-out hero in the game, and you decide to go raiding only to find defense teams composed entirely of maxed-out clones (that is, 5 copies of the same hero). Which clone team(s) do you think would be the most difficult to defeat, and why?
Some examples that I would probably reroll:
5x Isarnia (one is bad enough, but multiple simultaneous hits from her special would easily be lethal for anything)
5x Azlar (same reason as Isarnia, but perhaps a bit less lethal due to the lack of defense debuff)
5x Hel (no mana for you, ever)
5x Guardian Panther (the dark defense debuff would be very lethal when facing an entire team of fast-charging dark opponents)
5x Guardian Owl (if you strike one down, the others will become more powerful than you can possibly imagine…)
