I also think a budget-ish version of this deck would be highly playable and quite powerful relative to other budget options
Ill also point out that green legendary matters is something that weve been getting a slow trickle of lately, with Kolvori, God of Kinship on my Cube bucket list, in a similar space with Mox Amber
She takes things in a wildly different direction and while she compliments Satya well, you're better off finding something else to do with her entirely rather than swapping her as the front Commander here
Spells with split second only prevent new spells and activated abilities from going on the stack until those spells resolve, but once the spell with split second resolves, you're free to interact normally with any other spells on the stack
Either green gets stronger through even more redundancy, or it explores new space inevitably becoming stronger
It might be that theyve ran out of staples, or maybe theyre just disillusioned with the idea of homogenization when it comes to deckbuilding
