Spy Combo's artifacts are limited (Lotus Petal, Overgrown Battlement's mana ability is not an artifact, Food tokens), so Steel Sabotage has only marginal targets like a Map or Food token and is a speculative, low-impact include rather than a strong answer. This is fundamentally a green creature deck with no removal suite, so our Counterspell and Dispel are well-positioned to simply counter their key enablers like Winding Way or Lead the Stampede. Deem Inferior is weak here since it only tucks one permanent and doesn't address their wide boards from Saruli Caretaker and token generation. Keep the core engine intact and lean on efficient countermagic to disrupt their mana ramp into Dread Return reanimation.
