Necrobinder:
Having a 2nd health bar in Osty you can actively bolster makes Necrobinder very resilient. Souls are very good even after getting nerfed a few times. Ethereal cards exhaust themselves when you don't need them. Doom helps Necrobinder play defensively too.
I'm gonna say the same thing I hope for every time one of these nintendo things comes around.
I would really like a new Wave Race game and a new 1080° Snowboarding game. Or if they were both combined into one game that would be pretty cool too.
Silent:
Far and away the strongest character right now I think. Sly and card draw/discard is very good and can play a passive/defense style at minimal risk. Shivs feel strong as well. Poison feels underwhelming until you get accelerant or can stall with good defenses.
