How to get Strategy Cards?

Cost a lot but worth it. +4mcv and +1 spd to corners and +1 spd for wrs are my highlights....cost me about 300k

You can buy them. Random strategy for 5k in the Store. Exchange Sets are available as well to trade in lower to higher, I.e. common to uncommon, uncommon to rare and even rare to rare fantasy pack.

do the daily objectives (at least win 2 solos & buy 1 pack)
