After reading through some posts about this card and seeing the discussion about it, I'd like to bring in a new approach for balancing/reworking it. (5310-nerf-amii-monument, 6319-balance-proposal-amii-monument)
My idea would be to go away from "make its costs higher" and "make it t4", but rather does a little rework to open up new play styles with it.
- when activated, it will just stay active for a short period of time (like 10, 20 or 30 seconds)
- after that time it most likely needs a very high cooldown to reactivate (like 120 seconds or something)
