YO YOU CAN DO THIS?

I have no idea what mindset that player has but who builds the same units that aren’t merged up, seasonal/5* exclusives units are different in this scenario, but they could of merged them to +3 by now. I wonder if they have 11 5*s of the same unit, all built up as well...

This can work in arena where you only need to take one unit off the opponent team, but it's a terrible idea in AR def when the attackers can preview your setup and choose from five teams. One Naga tome or L.Tiki is probably the end of that entire team. They might at most lose one unit in the process, but the defense is going to fail very consistently.
