Seriously! He's very bad considering.
I mean what advantage does he have over other grapplers?
Lobo has the same setups but way better, because his combos do full damage and end in a 50/50 throw setup where Shazam's need to lose a lot to go back to that situation. He also has better throw traps on block.
Grundy's command throws also work on knockdown/block and deal as much meterless as Shazam's do with meter.
Frost has the same command throw setup on knockdown (223 > Dash > DBF2) and she gets insane damage for it.
It isn't like his normals or zoning are any better either. His normals are all short, unsafe, or super slow. His zoning is a joke in 90% of matchups.
Low damage, bad normals, inferior mixups, bad AA, VERY meter dependent, weak damage off of fast punishers, weak zoning, etc.
All he can do is get a knockdown and keep 50/50ing them (assuming he has meter) and other characters do that way better.
