VID link below. Some of these defense teams are getting a bit difficult to beat. I quite like the challenge, this is a great defence.
But…this power creep has all happened in just the last 4 weeks
Someone joked recently about the next hero doing 1 million damage and stealing all your gems, that is ridiculous of course… That won’t happen for at least another 3 months. 
Kill them before they can charge if you’re lucky is my strategy 
I’ve been testing it for my regular defense just out of curiosity. It’s been holding 2700+ cups for over a week now even when I log off from top 100.
Pretty sure some people are testing out attack teams but still surprised that it’s holding up.
Just keep in mind the more people that put these new heroes in their defense the more likely they are to get nerfed.
Theyl be putdated in a month or so and new problem heros will emerge.
