The baseline is fine, too
I like to keep Sensei's Divining Top in against combo decks in the off chance I'm able to float a counterspell on top of my deck and stop a key play
non creatures i would run: Lifecrafter's Bestiary, Skullclamp, Return of the Wildspeaker, Inspiring Call, Harmonize, Rishkar's Expertise maybe a few things like Fade from History, Beast Within, Nature's Claim, Collector Ouphe is also really strong since you will be running creatures Sure, the mana doubling can be fun, but is it really needed
Then each enchantment card in your graveyard has escape equal to it's cost and then three exiles
While Budew has made items harder to play, Eri sometimes locks them down for the whole game if a player is only playing one copy of a key item, which makes it useful in a variety of control decks
But if youre aiming for value, youll on average get about 1.5 mana per room and thats despite the slow start
