So my deck is Bangers/Leader

So in this deck there are:
Shann
Blaaster
Loocio
Graff
B Ball
Bennie
Massiv
and the Leader

Now if you say to me something like "but there are four 4* cards here!" but the thing is that the Leader would have a way higher chance of appearing since it is just 1card from 1 clan rather than 1 card in the same clan from 7 other cards. So I was either thinking Morphun or Ambre. Which one?

Either Hugo/Eyrik

I'd say 1. Hugo or 2. Eyrik.

Eyrik or Morphun

Morphun will work. Ambre if you want a sure 1st round win though.

Morphun. If he's banned then Eyrik.

This week Hugo works well to counter Caelus & Oshitsune. Otherwise Eyrik. Never tried Morphun but I assume he works with every deck

Possibly Morphun or Hugo !
with there bonus, Bangers have enough power as it is

And btw, Leader has an equal chance of popping up

Morphun would be my opinion. Eyrik would go great when Morphuns banned.
