Rhonas's first triggered ability affects only creatures you control at the time it resolves. Creatures you begin to control later in the turn won't have their power doubled or gain vigilance.
God-Eternal Rhonas
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.
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.
