Tribal Tribal Knows No Bounds - Morophon, the Boundless (EDH / Commander)

This deck is part of a "project", in which I'm building four separate five-colour decks, with some communal cards. The new shrines from Kamigawa: Neon Dynasty suddenly made the pile of shrines I had waiting to become a deck, more viable. When building a five-colour Shrine deck, I decided that, since creating a good five-colour mana base is so expensive, I'd also build some of the other five-colour decks I'd started to prepare for. I'm sleeving them all up in identical sleeves and keeping them in a deck box with room for four decks, with the communal cards (and a list of the communal cards) in one end of the box, so I just have to shuffle them into the deck I'll be playing. It will require more shuffling than normal, and it'll be an extra chore to remove the communal cards after playing, but I'll gladly do that to have a good mana base for all four decks. The four decks are (as of now): Go-Shintai of Life's Wisdom (Shrines); Morophon, the Boundless (Tribal tribal/Changelings); Dragons (The Ur-Dragon); Slivers (The First Sliver). I'm about to finish the Dragons deck and the Slivers are likely next in line.

The (current) communal cards are listed below:

10 fetch lands
10 shock lands
5 triomes (will consider what to do when the new "triomes" come out)
Exotic Orchard
The World Tree
Bloom Tender
Dryad of the Ilysian Grove
Lotus Cobra
Nature's Lore
Three Visits
Farseek
Utopia Sprawl
Smothering Tithe
Rhystic Study
Heroic Intervention
Beast Within
Generous Gift

I might remove some of these. I'll playtest and see. Input welcome.
