I like this list bro, I wanted to add Lir though, I am having a decent a success using him against Yodin Zaku, but pretty much this is also the summoners I use when I want to climb the ranks aside from Plado, I have never rented him maybe I will him soon.
Yeah bro, just put the top 10 legendary summoners on my point of view, I'm excited to get the new chaos legion summoner esp those from airdrops!
Good luck bro!
