So I managed to get one a few days ago when he came out but I’m not sure what sort of team I should be using him in. Does anyone have any suggestions for good teams with him?
Mercy
Alchemist
Hellcat
Gard
Dragon banner
Humility
Alchemist
Gard
Mercy
Holy banner
Try one of these two & let me know how it works for you.
Honor
Apothecary
Keeper of Souls
Gard
Broken banner
OR
Humility
Manticore
Alchemist
Gard
Progress banner
I play on mobile & PC but pretty sure console has all of this… super fast lots of damage with this setup
Unicorn Banner (not sure if on console yet)
tassarion
mad prophet
gard’s avatar
prismatic orb (either archer with fast or sorceror with final trait)
use tassarion first to choose purple and then mad prophet next prismatic orb to boost gards armor which will already be boosted if you have his traits and he will be ready to deliver one fell swoop 
and it looks like i misread his third trait xP not how it works unfortunately he builds armor as spells are cast not as match 4 happen lol
