To bring Clavigera Spores into play, you must have a ready Thinker. Remove any form or upgrade that the Thinker is supporting (if there is one). Place Clavigera Spores face-down underneath the Thinker, and engage both cards 2 turns.
When Clavigera Spores finishes being researched, it remains attached to the Thinker. If it is discarded, or if the Thinker is destroyed, its effects are cancelled.
