hard question, best way to stack against everyone, is to eliminate weaknesses that you may have. a general common weakness of aminers, tends to be missle, and some chemical. so basically defend against those paticular attacks. as far as specifics on races go, marus use tiger or angels(so far against me) in their first stacks. terrans spam herc and tyr, or if inexpirecend they will use p class in the front, for collectives, they tend to use galleons and sloops as a standard ship in their stacks, for guardians, you can deefend against the ruby and maybe torm spam, but hun-li is tricky, hence aminer`s missle ships arent all that great, and other aminer, use some neutral. and use neutral with all other stacks as well to offset the common weaknesses
good luck
