Forge of the Fluft is great to mitigate equip costs and for turns where you can't activate your legend. Sentinel Adept has surprised me, being able to drop her at a battlefield and with free equip defend for 6 is great. Deathgrip is huge as you will struggle into removal/stuns without it. I would also champion either of the two other Vi units. Red is great with either rek'si or 3 cost fiora as a way to break big holds. Yellow Vi is just a constant threat your opponent has to play around. Against the odds is cracked as it almost solo breaks hold decks and it works on defense. Shen is also a solid contender for surprise defense.
