Demonic Tutor lets us cut directly through that variance, selecting the perfect card we need at the moment in return for a generic and a Black mana
Imodane, the Pyrohammer If doubling damage output is your thing, Imodane, the Pyrohammer is a red commander you should definitely check out
Heavenly Hosts Angels are predominantly white, with some leaning into black or red
The model would either not respond or confuse cards, miss some or even hallucinate prices
Blastoise takes longer to evolve, and would need to be benched briefly while you get your ducks in a row, beefing up its energy with some Misty flips or pure patience, using another card upfront as an aggro starter or damage sponge
Coming at it from the other direction your list will also benefit more from raw draw effects and perhaps less from other value generators than average
