This card is easily, half of Echo's power. ATTACK and THWART triggers for Improvisation with lot of versatility to choose between damage or threat (or both!), play it once every turn by storing it in Echo and returning it via Muscle Memory (so it can return to Echo). Just First Aid your Daredevil from time to time and you are fine. With American Sign Language and Daredevil's discount, the combo is even free from any cost!

Do you feel like having a desire to rush for this combo? Add copies of Dynamic Duo and you will be lit in no time. Enjoy your lack of senses, because your enemies wont ;D
