2019-05-03 : If an effect exiles the God and immediately returns it to the battlefield, its last ability triggers but will have no effect. However, if an effect exiles it and would return it to the battlefield at a later time, the God’s ability may return that card its owner’s library first. If it does, the effect that exiled it won’t return it later.

2019-05-03 : If one of these Gods leaves the graveyard or exile while its last ability is on the stack, it will remain in its new zone, even if that zone is a graveyard or exile.

2019-05-03 : If one of these Gods would die and it’s your commander in the Commander variant, you may put it into the command zone instead. If you save your commander this way, it doesn’t die and you won’t put it into your library. The same is true if it would be exiled.

2019-05-03 : If the God’s owner has two or fewer cards in their library, the God is put on the bottom of their library as its last ability resolves.

2019-05-03 : If you control another player’s God when it dies, you decide whether to put that card into its owner’s library.

2019-05-03 : In a multiplayer game, if you put another player’s God onto the battlefield under your control, it will be exiled as you leave the game. If you were still the controller of that God, you would control its triggered ability but you have left the game; that ability won’t resolve and the card remains in exile. Similarly, if you lose the game at the same time that another player’s God that you put onto the battlefield is destroyed, it remains in its owner’s graveyard.

2019-05-03 : In the Commander format, a commander’s color identity isn’t affected by color words (such as black) appearing in its text. If God-Eternal Oketra is your commander, your deck can’t contain black mana symbols.

2019-05-03 : Oketra’s first triggered ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered.
