For this week's CCC, the prompt lead me to insects, a pile Deck on the cusp of playability (that's the copium speaking). While this card may look unassuming at first, it does a lot of things that synergyze with insect decks. It banishes Resonance Insect from your Deck. It banishes a Beetrooper to trigger Cruel Saturnas. It increases the destruction potential of Battlewasp Grand Partisan the Revolution. Did I mention that it banishes Resonance Insect?
Of course, the effect that summons from the Deck could be used unethically to pull a Scary Moth out and have its effect negated until your opponents turn then banished again with this once your turn comes back around. But why should Shaddolls have all the floodgating fun for themselves?
Art comes from Great Poseidon Beetle.
