Link

Link is a keyword which is similar to Legion in which it needs two specific units to work, but both units are from different clans or sub-clans. For a Link to work both units must be present on the field. When units are Linked when they battle they gain 5000 power for that battle in addition units that are currently Linked gain an extra skill.

How it Works
Links are prominently used in tag team battles in which case if the two required units are in either pair's fields (one partner has 1st unit while the other has 2nd unit) then both cards becomed Linked. If either unit gets retired or if another unit rides over one of the 2 units the Link is broken. The units may be located on a vanguard circle and rear-guard circle, a vanguard circle and vanguard circle, or a rear-guard circle and rear-guard circle for the Link to work.

When playing in a normal 1 vs 1 fight the 2 units must be place on the owner's field in order for the Link to work.

Example
