This isnt so much a build-around as it is a way to mess with the table
Even outside of specifically Energy decks in Modern, Ajani is likely getting a ton of Commander play
Oddly, our losses had one thing in common: they were both Arbor Elf / Utopia Sprawl decks, which seems like really difficult matchups for Mono-White Taxes since our opponents can make so much mana that our Thalia, Guardian of Thraben and Vryn Wingmare aren't all that effective
Oh, and all that, plus it gives you two passive lore each turn
Whenever you cast a spell whose name begins with the chosen letter, create a white 2/2 Cat creature token with flying
If it changes zones, it will either cease to exist (if it's a token) or cease to be a copy (if it's a nontoken permanent), and so you won't be able to cast it as an Adventure
