Each player may play an additional land on each of their turns.
At the beginning of each player's upkeep, if that player has no cards in hand, that player draws three cards.
The draw step is after the upkeep step, so drawing a card as a turn-based action wonâ€™t affect whether Ghirapur Orreryâ€™s second ability triggers.
No player may take actions in a turn before Ghirapur Orreryâ€™s second ability checks to see if it should trigger. If the player whose turn it is has any cards in hand, it wonâ€™t trigger.
In a Two-Headed Giant game, Ghirapur Orreryâ€™s second ability triggers for each player on a team separately. If one player has cards in hand, it can still trigger for the other player.
If the player has any cards in hand as Ghirapur Orreryâ€™s second ability resolves, the ability does nothing. Notably, a second Ghirapur Orrery wonâ€™t have a player draw another three cards unless the player empties their hand after resolving the first oneâ€™s trigger.
Ghirapur Orreryâ€™s first ability is cumulative if more than one is on the battlefield.
Ghirapur Orreryâ€™s first ability allows a player to play an additional land during their main phase. Doing so follows the normal timing rules for playing lands.
