Wow, a lot to disagree with here.
B-tier: what is
Rishkar's Expertise doing there? Conditional, expensive. Sure, it is almost mana neutral but still.
D-tier:
Night's Whisper is definitely better than that. C-tier material, easily.
E-tier:
Greater Good is about as restrictive as
Rishkar's Expertise. It's cheaper to cast, repeatable, free to use.
Ponder is better than that. Dig 3 or 4 gor just 1 mana??
How did you get Bob and
Phyrexian Arena that high? They're at least a category worse than what you're suggesting.
