Heres a quick list of two cards from each Historic set that fits our theme (except for Historic Anthology 2 which didnt really have any good fits): Elvish Visionary and Fauna Shaman from Historic Anthology Entrancing Melody and Wakening Suns Avatar from Ixalan Ghalta, Primal Hunger and The Immortal Sun from Rivals of Ixalan Shalai, Voice of Plenty and Guilded Lotus from Dominaria Vivien Reid and Goreclaw, Terror of Qal Sisma from Magic Core Set 2019 Next I decided to take a look at the sets that have come out since Throne of Eldraine, and see if there were cards there that stood out as good replacements for this deck
However, theyre fair game in Commander and Brawl, as well as any formats that use sideboards, including Limited
Immediately, I knew I wanted to do something with this
Then as your vehicles deal combat damage to your foes, you exile that many cards from their library and you can play them, although there is no mana-washing here, so in a mono-Blue deck you might find it rough to cast non-Blue, non-colorless cards
If you only want to play one color, that's a perfectly fine choice, but if there's an appealing card that you'd like to play in a second color, you can feel safe in doing so
