But Spike is not really good at all.
He's too fast both because of the input lag and the speed at which you move it's hard to recover if you guess wrong.
Spike, Mario, Peach
Bowser and Chain Chomp are actually pretty much broken because their backwards trickshot is so loose in timing and direction.
You can pretty much let everything that's not a dropshot go by you and time it with the back trickshot for crazy meter.
What makes this broken is that the only way to beat these characters because of their reach is to and power is to rally with them and beat them with energy which you can't do if someone does this.
Most chain chomps are Bowsers don't do this and super bad connection can make it hard.
Waluigi and Rosalina are plenty of capable of rallying and beating those characters; it's even enough to not cry about it. Because of their reach Rosalina's splices which make her OP to other characters aren't a huge factor.
You can beat a Bowser and Chain Chomp with Peach, Mario, and Spike only if you're way better than your opponent and highly-skilled.
Toad, Yoshi you might as well throw in the towel.
