Oh yeah, Boompile, Oblivion Stone, Perilous Vault and even Blast Zone are all amazing with Ashaya, Soul of the Wild.
You can get infinite mana with Argothian Elder, Krosan Restorer, Ley Weaver, just untapping themselves as part of the process.
With a few lands/creatures that produce more than one mana you can do the same with Hope Tender or Magus of the Candelabra, for infinite mana as well.
Basically a mana doubler would be the key here or Gaea's Cradle, Nykthos, Shrine to Nyx.
As long as a creature can produce at least 3 mana you can go infinite with the Hope Tender or Magus of the Candelabra as well, so Selvala, Heart of the Wilds, Incubation Druid, Karametra's Acolyte, Elvish Aberration, Gyre Sage, Llanowar Tribe. With enough Elves Marwyn, the Nurturer, Wirewood Channeler, Elvish Archdruid, Priest of Titania.
Mana doubler are; Leyline of Abundance, Nissa, Who Shakes the World, Heartbeat of Spring, Keeper of Progenitus, Dictate of Karametra, Mana Reflection, Zendikar Resurgent, Nyxbloom Ancient, Regal Behemoth, Vernal Bloom, Vorinclex, Voice of Hunger, Caged Sun.
Other cool little interactions; Arbor Elf, Quirion Ranger, Scryb Ranger.
Also look out for landfall as an ability as your creatures should enter the battlefield as a land. Lotus Cobra has just been reprinted, just saying.
Courser of Kruphix becomes a Soul Sister.
Avenger of Zendikar is going to count your creatures as lands, and then each creature you cast will trigger it.
Also things like Boundless Realms are way more easy to get incredible value as your creatures count towards it (as well as helping to cast it).
I've basically laid out the core for a deck, so I'll probably end up making a thread in the deck lists and try and come up with other synergy.
