Perhaps implement something similar to how it works on Pokemon Go. You have to be friends with the person you want to trade with. The more you use that friend in battles, the higher the level, each level gives gives access to different card types to trade. The starting level let's you trade SSRs, then as the friend level increases you can trade URs and TURs and at max level LRs. Also each trade would require zeni, if you're trading for a unit you don't have it'll cost more. Already have it? Less zeni. Maybe offer an LR as a mission reward for completing so set number of trades. Give players an incentive to do it.
