- 7 August 2020The power and toughness of the token change as the number of creatures you control changes. The token's ability counts itself, so it'll be at least 1/1.
- 7 August 2020An ability that triggers when a player casts a spell resolves before the spell that caused it to trigger. It resolves even if that spell is countered.
