A Legality Disappointment
I dont know of many cards that can punish greedy deckbuilding this cleanly
Mangara, the Diplomat With [c]Managara, the Diplomat[/c] in play, your opponent will be incentivized to hold off on casting multiple spells per turn and attacking with multiple creatures per turn
Wayfarers Bauble, Arcane Signet, Mind Stone, and Sol Ring are the cards youre happiest to see turn one or two, because this deck does nothing exciting until the manas ahead of the curve
Most Expensive Cards: Arabian Nights as expensive as a Mox or, in some cases, worth even more
Note the offense of Empyrial Armor (nice combo with Land Tax!) over the controlled elegance of Buehler's mana costs emphasizing his engine: #7
