PHC's to duplicate champs is my primary source. It does appear in alliance event prizes, but usually not very much.
When you dupe a champion, you'll get:
1* = T1 ISO (200)
2* = 2x T3 (825) and 1x T2 (350)
3* = 3x T4 (5000)
4* = 14x T4 (5000)
5* = not sure, never done it
Of course duped champs is the best, but if you are just trying to level them up, I have found the class specific iso boosts them more than the generic.

I'm sure duping a 4 star is 24 tier 5 not tier 4.
And duping a 5 star is also 24 tier 5 i believe.

5* = never done it, but I'm almost sure it's like dupe a 4* (but it don't give you shards).
For OP, everyone is right, the best place is duping champs. I would said it's virtually the only place.

I believe duping a 4* is 24x T4 ISO
Duping a 5* gives 24 T4 class iso
