- 29 September 2017The discarded cards just need to share one card type. For example, Rowdy Crew will get two +1/+1 counters if you discard an artifact creature and an enchantment creature.
- 29 September 2017The card types that can appear on the discarded cards are artifact, battle, creature, enchantment, instant, kindred, land, planeswalker, and sorcery. Legendary is a supertype, not a card type.
- 29 September 2017Once Rowdy Crew's triggered ability begins to resolve, no player may take other actions until it's done. Notably, you can't discard or cast any of the cards you draw to try to rig the results of the random discard.
