Hi, I prepare a 2vs2 game, and my partner and i will be use seraphon, we can use for example comets call with our kroak in the same turn or only can use 1 comets call because we are considered the same army
the "rules" for 2v2 games can vary. But usually you are considered as 1 "player" made up of 2 1000 point armies. this means that once per turn/phase abilities can only be used once per team, you gain 1 command point a turn per team and yes spells will be restricted to 1 instance of that spell per turn. so if you are both playing seraphon make sure you don't bring the same endless spells as you won't be able to use both and have your casters know different spells.
