A good otp champion

If Brand is mid don't even consider him. He is pretty weak lane phase and way more impactful as sup. I am thinking about Ekko, as it is the most versatile champ, who can go bruiser, assassin, tanky, as well as provide a little utility.

Out of these, I would go with Ekko.

Just because he fits into almost any Team unlike the others. Brand is weak on solo lanes Kata is weak if you get secoundary and has no cc Akali has no hard CC

Choose whichever you win the most with.

Kat's a good otp champ :^) I might be slightly biased though

Brand

Since you don’t have azir I won’t say Azir but for the fun and action I’d say kata kata my blade dagga

Wait for Akali VGU before you decide.
