Faerie Macabre can discard itself to exile cards from graveyards, which strips the instants and sorceries that make Tolarian Terror and Cryptic Serpent cheap, and also hits their self-mill fuel from Thought Scour and Mental Note before it piles up. Scattershot Archer kills Delver of Secrets once it transforms (it only has flying on its transformed face, where it has 1 toughness) and can repeatedly snipe it when they rely on it for pressure. Cut our slower value pieces since we need efficient answers to their card-selection-into-big-threat plan rather than more raw card advantage. Keep our core mana creatures in since we still need to out-value them on board once their counterspells are exhausted.
