eldrazi displacer thought knot seer triggers
Hi,
After the Displacer's ability is done resolving, we have two triggers waiting to go on the stack: the Seer's leave the battlefield trigger and the Seer's enter the battlefield trigger. Assuming the same player controls both triggers, they can put those triggers on the stack in any order they choose. They can either exile a card from the opponent's hand, then have the opponent draw a card; or they can have the opponent draw a card, then exile a card from their hand.
