Azorius Standstill wants to lock us out of casting spells and then close with Wrath of God, Decree of Justice tokens, or an animated Mishra's Factory/Faerie Conclave, so our plan is to play around Standstill by not overcommitting while still applying pressure. Naturalize is a real and useful include here: Standstill is a {1}{U} Enchantment, so Naturalize can destroy it to break the draw-three symmetry on our own terms, and it also answers Powder Keg, a {2} Artifact that threatens to blow up our tokens and small Goblins. Red Elemental Blast comes in to counter or destroy key blue permanents and spells like Counterspell, Fact or Fiction, or an animated Faerie Conclave. We trim Mogg Fanatic and Goblin Sharpshooter since Wrath of God punishes overextension, and we'd rather hold some gas back than dump our whole hand into a sweeper.
