- 24 January 2025If you cast a spell “without paying its mana cost,” you can’t choose to cast it for any alternative costs. You can, however, pay additional costs. If the spell has any mandatory additional costs, those must be paid to cast the spell.
- 24 January 2025Tamiyo’s first ability can target creatures you don’t control. You’ll draw a card, not their controller, if they deal combat damage.

- 24 January 2025If Tamiyo’s first ability targets two creatures, and both deal combat damage at the same time, the delayed triggered ability triggers twice.
