400 hp for every successful magic mark hit, and even more when you add Kill To Heal and Life Rip. Basically, a lot of self sustain with a little bit of a scamper heal. It's recommended if you use Scamper since it the most useful, Boom Boom is fine just remember that the Greater Good Card only effects those who have the full magic mark, you'll have to purchase Life Rip in order to benefit from the AoE part of Boom Boom. I alway find Nimble on Moji very useful since, for a flank, she's pretty slow and the extra speed can help her catch up to her target if she turned them into a treat.
Things to have in mind-Cauterize can still screw you over so be carefully and choose your fights wisely.
-This loadout mainly focuses on Moji's Scamper, there's no cards that will benefit Magic Barrier.
Random fact: if a Ash used her ult and you have yours, you can still execute Ash with it.
