What if we in addition to the other effects of CU (preferably not the current ones) also got the ability to let everyone inside the bubble get the buff from the card in our current Spread? Someone somewhere suggested a similar thing but with random buffs, although I didn't seem to be able to find the post in order to give full cred to that person. Giving everyone the full effect of the currently spreaded card (as opposed to halved potency with expanded RR) could be one way to boost our buffing capabilities, but I don't know if it would be too powerful even if the spreaded card was consumed in the process, but it's an idea anyway. Random buffs could work, but we do want our buffs to be as controlled as possible. Still situational of course, but very effective in battles which encourage stacking.
