I have Combat Pheromones (CoTA 180), “John Smyth” (CoTA 195), and Mindwarper (CoTA 196) in play. I sacrifice the Combat Pheromones and reap with Mindwarper, and then reap with “John Smyth” and use “John Smyth’s” "After Reap:" effect to ready Mindwarper. Can I use the Mindwarper again?
Yes, Combat Pheromones is granting permission to use a creature during that turn. If you have an effect that readies one of the Mars cards affected by the Combat Pheromones (Such as “John Smyth”), you will be able to use that card again.
