3 rulings from Wizards of the Coast
- 12 April 2024Players pay all costs and follow all normal timing rules for cards played from exile with Memory Vessel's ability. For example, if an exiled card is a land card, its owner may play it only during their main phase while the stack is empty.
- 12 April 2024Memory Vessel has received a minor update to its Oracle text to clarify that players can play only cards they exiled from their library during the effect of the activated ability, not the Memory Vessel that was exiled to activate the ability.
- 12 April 2024Players may still play cards from zones other than their hand if something would allow them to do so.
