How does Mask of Foresight work in 2v2 games, specifically whether the buff applies to teammate units?

Ruling: Mask of Foresight's "friendly" designation applies to teammate units as well in 2v2 games. Both you and your teammate's units receive the buff based on how many Masks of Foresight you have.

Nuances:

• When your units attack/defend alone, they get +X based on how many Masks of Foresight you have
• When your teammate's units attack/defend on their turn, they receive the same buff
