Serious post about Wrath now. It was honestly unexpected (and unfortunately unpleasant) to see such a defensive Sonic, since his strongest representatives have moved toward tempered aggression. I don't recall seeing anyone play like that since the StaticManny of old. However, I feel like StaticManny's camping focused on using Sonic's mobility to run away from the opponent; on the other hand, Wrath's camping is centered around creating a low commitment threat by continuously using shield canceled Spin Dash, and leaving his opponent guessing when he'll release it. This style honestly seems incredibly difficult to deal with if the opposing character has no consistent or high reward tool for dealing with Spin Dash and shield mix-ups, and I could see it being optimal Sonic play in many MUs. If that is the case, you would basically be playing a large number of guessing games to try and call out Spin Dash until you build a big enough lead such that this style becomes unfeasible; Sonic holds all the cards in this scenario.
Also, I'm surprised Larry's DK lost so badly to Trela. DKWill beat Venom fairly handily at GOML last weekend, and while Trela is stronger than Venom, Venom is no slouch with Ryu. Larry just was not able to land grabs, and spent most of the match in DK's horrid disadvantageous state. I personally feel this is a decent MU for DK, since he's able to space outside of Ryu's effective range with his tilts and bair, and can pivot grab approaching aerials given Ryu's very committal jumps. I think
Emblem Lord
said something about this MU being good for DK as well, and he'd probably be able to enunciate it much better and more accurately than I can.
