Cards in a powered Cube tend to fall into three buckets: the "fair" bucket, the "unfair" bucket, and the "broken" bucket
Originally, I wanted to add counter magic to stop interaction, but I decided to use single-target protection to also trigger Nadu, so I included Blossoming Defense, Royal Treatment, Snakeskin Veil, and Tyvars Stand
Mill decks will definitely be including this Jace Variant, as its ultimate ability is too tempting and hilariously mean to resist, and counter manipulation via Proliferate makes it that much easier to activate
However, if you do choose a target, and that target is illegal at the time Spider Food tries to resolve, the spell won't resolve and none of its effects will happen
For three Energy, their Continuous Lick move is extremely overpowered, especially for a card that isnt even an EX
