Please note, this isn't a discussion regarding Amii Monument, I am proposing a new card.
Amii Monument allows you to have 5 orbs, when typically, you'll only have 4. I like this functionality but believe a new card would serve this functionality better. A new, far weaker version of Amii Monument.
Proposition:
4-orb (neutral).
100 cost (or similarly cheap).
Semi-unique building (all players can spawn one each, but only one).
Orb-switching is free (or cheap), and has no cooldown.
Alternative proposition:
4-orb (neutral).
200 cost (or similarly moderate cost).
Non-unique building (all players can spawn as many as they want) (like a normal card).
Once an orb has been chosen, it is locked in, and cannot be changed.
A card like this would open up some fun 4-orb plays. It would allow players to create some versatile and mixed decks, particularly allowing players to incorporate high level spells into their decks (i.e. nature spells). This would also allow decks using 4-orb pure cards to have a bit more options when playing.
Thoughts?
Edit: current Amii Monument means that people can't use 5-orb decks consistently for PvE. This suggestion allows people to reliably use 5-orb decks without having to consult other players nor limiting other players from using their own 5-orb deck.
