In Cometh Battle, there are some cards that deploy orbiters.
Orbiters are your allies. They are deployed just in front of you with a maximum of 6 orbiters, to either protect you, heal you, deal damages to enemies etc. They are deployed by cards you play in-game.
Medic orbiter adds power to its owner at each end of turn.
Fighter orbiter deals damage to opponent at each end of turn.
