If you don't, create a Treasure token.Whenever you cast a spell you don't own, put a +1/+1 counter on each Scout, Pirate, and Rogue you control
There also isn't a card like Treasure Cruise or some other high velocity and cheap card draw spell in the format either
So long as the color is represented somewhere in a cards mana cost, it can block an intimidate creature with the same color
I feel like the Assassin's Creed designers had Etrata in mind when designing the set because there's so many cards here that work with her specifically and no other legendary in the set: Roshan, Hidden Magister is the most notable example here, turning ALL of our face-down creatures into Assassins, giving them menace, and adding card draw to when we flip them up
Dont get us wrong, there are still some fun Commander cards here, but the set does add a lot of new cards for Modern players in different established strategies, and may well even create a few new decks as well
Its the fact that you have so many different artists and they all kind of blend their talents into coming up with one art style
