The top five: Brainstorm (blue, 1 mana): Instant, draws three and puts two back, letting you stack your next draw
The other big change with this set is the addition of dual-color cards, and the Belle and Beast deck certainly seems to be trying to get more use out of them than Jafar and Iago
One of the strongest Sultai cards, the biggest reason Muldrotha isnt a true cEDH commander is that it doesnt contribute much to most combos by itself and has a prohibitively high mana cost in that environment
When building a deck for a less cutthroat game in mind, the same principles apply
In short, The Scarab God is simply the best card in these colors for a variety of deck archetypes, and tokens are no exception since you get token generation and payoff in an efficient 5/5 body for 5 mana
Hes also arguably the only good option for a Mardu Vampire commander
