Still, her 0 and -2 is where shes going to do the most work, and its great you can choose to play her on either 5 or 6 This will have its moments, but this format also has a lot of tokens and creatures who give you value when they die, and when your opponent has those to sacrifice this wont feel worth a card at all, even with the poison counter on top If you can kill something with this, or have it help you win combat, it will feel pretty good since youre only spending a single mana

This card is one of my few exceptions since it doesn't have native double strike, but youll be attacking alone with Rafiq of the Many quite a bunch
