5 rulings from Wizards of the Coast
- 19 March 2021Sorcerous Spyglass affects cards regardless of what zone they're in. This includes cards in hand, cards in the graveyard, and exiled cards.
- 19 March 2021An activated mana ability is one that produces mana as it resolves, not one that costs mana to activate.
- 19 March 2021You can't choose the name of a token unless that token has the same name as a card.
- 19 March 2021You can choose any card name, even if that card doesn't normally have an activated ability. You're not limited to the names of cards you saw in the opponent's hand.
- 19 March 2021Activated abilities contain a colon. They're generally written "[Cost]: [Effect]." Some keyword abilities (such as equip) are activated abilities and will have colons in their reminder text. Triggered abilities (starting with "when," "whenever," or "at") are unaffected by the last ability of Sorcerous Spyglass.
