As the runaway train of new characters continues, I was thinking there were many characters from lower tiers that could have become more. Here’s my list, but feel free to add your own.
Juggernaut! - a higher tier version that hits hard, with low AP costs, High Health but inflicts self-damage
Ares - another beater that could have become more, with 3 hard hitting reckless powers that strike fear in opponents.
Moonstone - her high health still doesn’t make sense to me, but she is both offense and defense. A higher tier version could specialize in stealing and buffing tiles, plus specific board manipulation.
Scarlet Witch - given that she’s one of the most powerful Avengers, she deserves a 5* version.
Vision - for someone that has an infinity stone, can fly and can change his density at will, you would think he deserves more than 3* status
The Hood - one of my favorite 3s who suffers from a low health pool; with Dormammu on his side, he deserves more. He could be similiar to 5Strange who has a great passive but still low health.
Quicksilver - his powers should match his abilites, fast damage and AP generation. How about a passive board shuffle every turn that deals both damage and generates AP. That alone would make him awesome, unpredictable and fun to play.
