- 8 December 2022You can tap any untapped creatures you control to activate Cryptic Gateway’s ability, even ones you haven’t controlled continuously since the beginning of your most recent turn.
- 8 December 2022The two creatures you tap to activate the ability don’t necessarily have to share a creature type, but the creature card you put onto the battlefield must share a creature type with each of them. For example, you could tap an Elf Wizard and a Human Warrior to put an Elf Warrior card onto the battlefield.
