cards you should run 3/4 of as of right now:

creatures: old-growth/cavalier/delighted halfling(weakest link as it's still far too easily killed in the current meta and later on becomes a big dead draw)

Instant, Sorcery, Enchantment, Artifact utopia sprawl and your pick of either tooth and nail/storm the festival depending on the version you prefer.

lands: nykthos, shrine of nyx

planeswalkers: kiora/karn

the rest of the cards

 --------------------------------------------------------------------------------------------------------------------------------------------

different versions:

--------------------------------------------------------------------------------------------------------------------------------------------

storm the festival: https://aetherhub.com/Deck/h-green-devotion-957735

if you are storm the festival based limit yourself to creatures that cost 3-5 so that storm can pick them

 --------------------------------------------------------------------------------------------------------------------------------------------

tooth and nail: https://aetherhub.com/Deck/h-green-devotion--962444

the tooth and nail version of green devotion is more open minded towards what it can/want to run but right now it definitly wants to run xenagos, god of revels + worldspine wurm, vorincles \\ the grand evolution becomes a even better payof as now it has better potential targets but titan of industry, ulamog, serra's emissary and many other cards become available as storm the festival doesn't limit us anymore, check the maybeboard to see what new creatures we could use.

--------------------------------------------------------------------------------------------------------------------------------------------

Any devotion version that doesn't run green mainly with maybe a small splash for 1-2 creatures has less mana through devotion which is a big deal for this deck archetype, and not even necessarily better creatures(green creatures on arena are just that good) so just see these following decks as "fun alternatives to the meta" that still probably performs decently to some extent and are probably somewhat combo oriented to make up for it's lack in mana.
