Card Rulings

8/25/2017 Scalelord Reckoner’s triggered ability resolves before the spell that caused it to trigger. The ability will resolve even if that spell is countered.
8/25/2017 If the only nonland permanents on the battlefield are Scalelord Reckoners and Dragons controlled by players who control Scalelord Reckoners, any spell or ability that targets one of those Dragons will cause an infinite loop of triggered abilities and the game will immediately end in a draw.
