Its depend on your cost capacity to contain all of these, coz *7 will cost u lot of space.

My suggestion is to builld balance squad with :

1. Critical / Spark Buffer (Zenia, Colt, Dion)

2. Mitigator unit (shera or darvanshel, but I suggest Shera instead)

3. Unique unit with special characteristic (Tridon, Ultor)

4. BB boost unit (ruby)

5. Status nullify or negate unit.

Its not perfect, but I hope it is helpful
