Hydroblast and Blue Elemental Blast are excellent here, cheaply countering or destroying Fiery Temper, Lightning Bolt, Lava Dart, Kessig Flamebreather, and Guttersnipe, since nearly every opposing spell and relevant permanent is red. The exception is Sneaky Snacker, which is blue and black, so neither card can touch it. This is a race, so trim slower or clunkier cards like Salt Road Packbeast, Leonardo, Big Brother, and Ornithopter for cheap interaction that also disrupts their damage-trigger engine. Thraben Charm and Dust to Dust stay in the board. Sneaky Snacker returns from the graveyard to the battlefield tapped when its controller draws their third card in a turn, and neither Hydroblast nor Blue Elemental Blast interacts with it. Prioritize killing Guttersnipe and Kessig Flamebreather on sight to blunt their damage triggers.
