Buy whatever you need, it depends on what you already have. Elder Kais are always useful, and so are Hourglasses. But in terms of units, only you know what you need.

Definitely do not waste time and resources to raise AGL SSJ Goku's SA, he's just a support unit (Ki +2 for all allies when HP is 50% or above), it's not worth it.

will soon dokkan awaken into, if that interests you.
