Basically need to use Heimer or Ahri to beat a 5 star challenge. Problem is I don't have Ahri and Heimer seems a little slow.

I have him max stars(3) and level 28 but I have no idea how I'm supposed to out resource opponent that get 4 or 5 free units turn one(Swain) or have all that bs (Lyss).[tangent] I really hate Lyssandra, the game had enough tough c9ntent already the Asol fight were hard already but the devs made something that counters everything? So lame.

Anyways.

Is it possible to beat any 5 star in 2 days before the mission expires I really want the blue(diamnon) Vault.

Oh yeah and I don't have any epic that buff Heimer so idk what rare help him I used chapter, Duplicator and the comet spell one.

And it would be nice to have a new Champ win right after maxing him. I enjoy Heimer he can be so broken (in.lower difficult ceiling).
