I split this up by function rather than card type. At the bottom, I'll include a bunch of other ETB creatures I considered but didn't go with - either for practical reasons, affordability or personal flavor preference. Note that Elemental Bond can get out of control here - you don't want to mill yourself! Please let me know if you have any advice.
Unplayed Conjurer's ETB deck (I need a catchy name - something about tokens?)
I also have a deck built around that and Dominus of Fealty (discussion thread here: https://www.mtgsalvation.com/forums/the-game/casual-multiplayer-formats/810350-lets-build-a-steal-forever-deck)
If you want the final list of that deck, too, let me know.
