2 rulings from Wizards of the Coast
- 20 September 2024You follow all timing rules for spells cast and lands played using the permission granted by Valgavoth's last ability.
- 20 September 2024The spells you cast using the permission granted by Valgavoth's last ability have an alternative cost that's paying life equal to their mana value. You can't choose to pay their mana cost and may not pay any other alternative costs. You may still pay for additional costs, such as kicker costs, and you may pay mana for those as normal. If the spell has mandatory additional costs, you must pay those.
