Attack buffs from leader skills, spheres, and from unit buffs are in a different category and CAN be stacked. Leader skill attack buffs can be stacked, spheres can be (if applicable, e.g. Ihirs Guise and Heresy orb as of now), but unit buffs cannot be stacked (e.g. Michelle's ATK buff will not stack with Zergel)

So No, Masamune/Angelic foil will not interfere and WILL stack :)
