Is this okay?
First of all, YES, One tournament doesn't really mean anything.
But as we all know, it's not only one tournament, this latest 3*+ tournament just showcase what we all know is happening.
The meta is not *adapting* spider99, it's adopting it, just yesterday I played a tournament with 34 players and it had 8 spider99. (I played against 3 of them and won all 3 matches, this is not a "I lost to X deck post")
I don't think the commander itself has to be banned but something should be done about it, it has all the insanely good blue control shell, the commander can be 2 mana removal and you can threaten an OTKO at turn 4.
Either the haste stuff has to be banned, it only really matters for spider anyway, it wouldn't hurt any other deck, or something else, I don't know what, but something.
