try blood queen or yuta

I got yuta a while back, so I'll use him @@kkarambaagfn2211

you should also be able to use this set in challenger but place more unit before upgrade farm

Ice shinigami*

use your strong blue unit

Shanks is good

Madara evo

Whitebeard may work

Ye

If not, the other strong blue unit should work

You can use coyote evo/red archer/rimuru evo pair with fujitora
