4c HollowOne dumps its hand with Burning Inquiry and Faithless Looting to cast cheap Hollow Ones and set up Vengevine, so Surgical Extraction can exile a graveyard Vengevine before they cash in on the discard-heavy plan, denying a huge tempo swing. Pyroclasm sweeps their small bodies like Blazing Rootwalla and catches Marauding Mako before it grows out of range. Eidolon of the Great Revel is risky here since cycling is an activated ability rather than casting a spell, meaning it won't trigger Eidolon while your own cheap spells trigger it repeatedly against you, so it stays out. Race carefully — their curve can dump a lot of power onto the board in one turn via Vengevine returns, so timing your removal to catch their explosive turns matters.
