If you have all these clans then I would go Ulu for first 6 then change to Morphun and use Nightmare or Uppers. In low pill rounds you need one hit shots and attack to gain your pills back with Ulu it's a bit risky so Nightmare for cards like Kenny and Kolos where you only need one shot or Uppers where you have cards to drain the opponents pills.
