This is the mirror-ish matchup against a slower Izzet value deck built around Agatha's Soul Cauldron and Vivi Ornitier; Spell Pierce protects your own threats and stops their key payoffs on turns 2-4 when they're most vulnerable. Scorching Shot's 5 damage cleanly answers anything they can put on Agatha's Soul Cauldron or a buffed Vivi Ornitier, which Burst Lightning's base 2 damage often can't handle. Trim Boomerang Basics since bouncing a permanent does little against a deck with few tempo-sensitive threats and plenty of instant-speed responses to punish it. Keep Reckless Rage and Academic Dispute as your primary removal since they scale better against their 2/3 Nightmares and Quantum Riddler.
