I got my new arsenal box today from gencon order. and I noticed they have a nexus of power card that reads different than previous nexus of power.
the new one says you heal 1 damage after spending one or more soulstones for any action other than damage prevention.
whereas the previous nexus of power states than after using a soulstone you heal two damage, with no other restrictions.
so, do we have to use the new nexus of power upgrade in place of the old one?
