Using Free admission and Dark portal to draw and discount your combo pieces, the ideal full combo is Ashtongue, Silas the Ashtongue, 3 Artificers (duplicated with Felosophy) then Soulfire the enemy Ashtongue for 32 damage to the opponents face. Getting this combo by turn 9 or 10 is surprisingly not to difficult, and Warlock is great at control enough to survive until then.
