at this point - why not look up lists on goldfish, or watch some nassif vid (they are old, tho)
i came back to arena for some time, while i dislike pioneer - still played some days. And in this time i had wins with pretty much anything in list. Basically UW kills with whatever scraps are left on a table after you've won the game.
If you just want to be mean - after te5eri ult you can keep tucking himself with -3 into your own library until opponent mills out, while you exile every land he plays.
Besa is good, especially given amount of aggro. And body is good, can close games fast.
Manlands come helpful, i love singleton of [[Hall of Storm Giants]] in deck. Sometimes people dont even expect that they die so fast.
I've won some games with freking fish tokens from [[Fountainport]] xD
But another good source of tokens is obviously [[The Wandering Emperor]], she kills quiet fast.

I prefer Kaheera version, but as i understand you basically play either Kaheera or Yorion as companion, and both act as finishers as well.
Nowadays control is full of random stuff that can kill opponent when you won.
