Containment Priest is a key hate piece here, stopping Show and Tell from cheating Atraxa into play. It does not answer Aluren, since creatures cast for free through Aluren are still cast and so are not exiled. Null Rod cuts off Lotus Petal's mana ability, slowing their Aluren combo and Show and Tell starts. Surgical Extraction can strip a key enabler like Aluren or Show and Tell once it hits the graveyard, taking the other copies from their hand and library as well. Static Prison and Hexing Squelcher are too slow and narrow against a combo-oriented deck that wants to go over the top; prioritize disruption and pressure instead.
