Rulings (2)
- Riddleform's first ability resolves before the spell that caused it to trigger but after targets for that spell are chosen. It will resolve even if that spell is countered.
- If Riddleform becomes a creature the same turn it enters the battlefield, you can't attack with it unless it gains haste.
