On this team SS2 Caulifla should be a floater, her links are not the best and her damage output is kind of underwhelming compared to the top-tier units in the element; her main purpose is to mitigate damage with her built-in Dodge and possibly counter a Super Attack.
"Universe Survival Saga"
So far SS2 Caulifla is one of the best options for this team; she is a very powerful unit and all she really needs to fit in is the "Tournament of Power" link. Ideally you would want SS2 Caulifla as a floater or on rotation with [Dawning Supernova] SS2 Kefla.
SS2 Caulifla receives a 30% DEF boost when launching her Super Attack that lasts for 3 turns, meaning she is going to be able to stack it if she is on rotation, but her multiplier being only "supreme" is sort of a detriment.
SS2 Caulifla has a very versatile Leader Skill: giving 2 Ki and 70% to all stats to all types, she is actually one of the best "rainbow" leaders in the game.
SS2 Caulifla receives a 90% boost at the start of the turn, which is respectable for a non-Dokkan Fest unit, a 50% chance to dodge enemy attacks and another 30% chance to dodge and counter Super Attacks. Her multiplier when she counters is actually the same as Unparalleled Golden Ki Super Vegito and Ultimate Super Saiyan] SS4 Goku's, two Dokkan Fest exclusive units.
SS2 Caulifla's main problem are the links: awakening through Story Event medals means no "Fierce Battle" and in this case that leaves this unit with only Super Saiyan as an ATK link, hindering even more her damage potential. SS2 Caulifla has a lot of Ki links, she can link amazingly well with SS2 Kefla and Kale Berserk, but that's about it, if we put her on rotation with them the links they share are pretty much overkill, most of them are pointless. Prepared for Battle is very good for Super AGL and Tournament of Power is the most common Ki links on a "Universe Survival Saga" team.
SS2 Gohan (Youth) is support unit that shares both "Prepared for Battle" and "Shattering the Limit" with SS2 Caulifla, he can activate "Super Saiyan" and "Golden Warrior" for her and give her an additional boost to make up for her lack of ATK links.
Super Vegito and SS2 Caulifla share "Prepared for Battle" and "Golden Warrior" for 3 Ki and activate "Super Saiyan" for each other; in addition to this, if Super Vegito launches his Super Attack before SS2 Caulifla, he is going to give her an additional 30% boost.
It wouldn't be an exaggeration saying that, linked together, these two units would probably be able to Super Attack consistently even without receiving any Ki at all from the Leader Skill; "Battlefield Diva", "Warrior of Universe 6", "Shattering the Limit" and "Tournament of Power" add up to 9 Ki, automatically giving them a Super Attack even under a 2 Ki Leader Skill. "Super Saiyan" is the only ATK link that SS2 Caulifla and SS2 Kefla pretty much have, so at the very least that one is active.
SS2 Caulifla has even more links in common than with SS2 Kefla with this unit, giving each other 11 Ki and making them automatically Super Attack even under a 0 Ki Leader Skill. No ATK links are shared, which brings us back to these units' main problem.
SS2 Kale is an amazing support unit and she is even obtainable in-game: her Passive will give SS2 Caulifla 2 Ki and 30% ATK and DEF in addition to activating "Super Saiyan" and most of her Ki links.
Some people might be tempted to invest for this unit in Dodge, to further increase her innate ability, but because of her lack of ATK links and her lower Super Attack multiplier, I would advise to still go for the standard lv.11 Additional and lv.15 Critical.
