@pinyin I'd replace one of the less useful ones (like Kaiser) for the Resistance link. 6 seconds of invincibility upon reviving can be really useful in bosses like Magnus and CRA.
Also the Kinesis link is probably more useful than the Jett link (most of the time, the main downside of the Jett link is that it's kind of a pain to keep up). I assume this is an old list though.

Here's how I usually go about it. Note that for all links besides Zero's I am assuming level 2, which means you got the mule to level 120. Also note that the order is not significant beyond Mercedes, who can help you make all the other mules faster for obvious reasons.

Mercedes (15% Experience boost)
Zero (10% PDR and -15% Damage intake)
Demon Avenger (10% Damage)
Demon Slayer (15% Boss Damage)
Jett (randomized All Stat and Attack/Magic Attack boosts - boosts are almost always better than Hayato's link)
Luminous (15% PDR)
All 5 Cygnus Knights (longest one to get, but their links stack and give a maximum of 25% Status Resistance)
Kaiser (15% Max HP)
Cannoneer (All Stats +25, Max HP and MP +10%)
Phantom (15% Critical Chance)
Xenon (10% All Stats)
Kanna (10% Damage)
If you are playing on Reboot, just swap Zero's for Beast Tamer's
