Travelling Chocobo, Sazh's Chocobo, Mossborn Hydra and Larval Scoutlander interactions.

my opponent had 2 travelling Chocobo's out, 2 Sazh Chocobo, a Mossborn hydra, Tifa and a Larvel Scoutlander. THe mossborn was bumped to 2048/2048 and stationed onto the Larvel Scoutlander I'm at 35 life and the Sazh chocobo are at 17 and 16 power.
The attackers left unblocked are 16/17 Sazh, 3/3 Travelling Chocobo and Larvel. THe mossborn Hydra was not attacking as it stationed.

my life total after combat was -495 yet there only ~40 total incoming before blocks. I think there is an odd interaction with Travelling Chocobo's and dmg being dealt.
