After testing for a while, it seems despite the data saying otherwise, the revived units don't receive any buffs. There's no part of the unit data which would suggest it happens this way (by the usual rules it would be revive -> buffs -> damage), it just does.

Seems to be an issue with the revive effect itself actually having some delay, possibly due to the animation.

Sorry to get your hopes up guys.

As for whether this is intended... no idea. It's possible Gumi thought it'd apply the buffs too, seeing as they made a point of having it be different from other unit. Including JP units, this is the only incarnation of the revival effect which occurs before buffs in the same frame.

Thanks to /u/Sellihca for bringing it up.
