2 rulings from Wizards of the Coast
- 23 August 2019The triggered ability of Thalia's Geistcaller will resolve before the spell that caused it to trigger but after targets have been chosen for that spell. It resolves even if that spell is countered.
- 23 August 2019You can sacrifice any Spirit you control to activate the last ability of Thalia's Geistcaller, not just a Spirit token it created.
