I think I know the answers, but I wanted to check. New Covenant (Jeremiah) has a unity identifier as listed below. Does this mean it only requires unity if played as an artifact, or because it's a covenant it's also an artifact and so the unity applies to the entire card?

Also, if the enhancement requires unity, does that mean the shared brigade must be either clay, green, or teal, or can I use it in a Blue Genesis deck since they all share blue (and use it on Jacob or Joseph since they're also green)?

Card text:
A New Covenant
Artifact has Unity: Heroes (Share a brigade)
 
Enhancement: Clay/Green/Teal, 3/3
Convert all evil humans in battle. You may draw 1 and topdeck this card.

Artifact: Shuffle this card: Your human Hero gains "May band to a human." this turn.

Cool, that's what I thought. Thanks

Thanks, that makes sense.
