Unholy Heat kills Ragavan, Nimble Pilferer and Phelia, Exuberant Shepherd cleanly, and with delirium active it can even answer a Casey Jones, Vigilante or similar midsize threat. Spell Snare is live against their two-mana spells like Phelia, Exuberant Shepherd or No More Lies. This matchup is a grindy race against a deck with plenty of removal and card selection of its own, so efficient answers to their early threats matter more than combat tricks. Keep the plan light since they already have Consign to Memory and Spell Snare of their own to fight over the stack.
