Mono-White Aggro aims to flood the board with Thraben Inspector and Raffine's Informant tokens, then close with Battle Screech fliers and Guardians' Pledge before you can assemble the combo; your primary goal is to protect a live Tireless Tribe long enough to untap and go off. Prismatic Strands is exceptional here—it neutralizes their entire combat step and can be flashed back from the graveyard via Faithless Looting or Pursue the Past, buying multiple turns if needed. Their post-board Standard Bearer is the most dangerous card you'll face: it must be the target of any spell that targets permanents, which directly prevents you from targeting Tireless Tribe with Inside Out, so answer it with Lightning Bolt or Electrickery before attempting to combo. Flaring Pain invalidates both their Prismatic Strands and any Martyr of Sands life gain that would otherwise pad their life total. Electrickery as an instant sweeps their 1/1 weenies and clears Standard Bearer off the board cleanly.
