UPDATE 1/8/2023 - I have removed all of the infinite combos from this deck because I am starting to prefer playing without them. I will leave this section of the primer intact as a reference guide for anyone who wants to play that way. That being said I have created a cEDH version of this deck were all of the below listed combos and them some can be used to their full advantage. That deck can be found here...
There are currently 97 different infinite mana combos is this deck, with quite a few more if you take into account all the different ways to satisfy the requirements for Marwyn, the Nurturer and Selvala, Heart of the Wilds.
With infinite mana we can draw the entire deck using Staff of Domination, but that's almost never necessary.
There are some additional combos that will draw the entire deck (listed at the very end), but since they create infinite mana as well, they're also almost never necessary.

Any of the Ashaya, Soul of the Wild + Quirion Ranger + X combos will allow us to draw the entire deck when paired with Beast Whisperer / Glimpse of Nature / Guardian Project / Soul of the Harvest / The Great Henge or if we have Mana Reflection / Nyxbloom Ancient in play we can use Lifecrafter's Bestiary. Drawing the entire deck is cool, but not really necessary if we're already creating infinite mana and have access to our commander.
