First soul: skip for the arcana pack in ante 1 to give you a triboulet.
In first ante 2 shop, open buffoon pack to get chaos, roll once to find a blueprint, buy it, then open spectral pack to ectoplasm the blueprint.
Around ante 5-6 is another spectral pack with another soul in it, giving yorick. HOLD ON TO THIS YORICK. Because in ante 6 is an arcana pack with another soul in it, which also gives yorick. What it would be if I still had yorick I do not know.
Unfortunately I died due to The Plant on ante 7, but if you can get past that you're smooth sailing.
