Once per turn, when exactly 1 "Super Defense Robot" monster or "Orbital 7" (and no other cards) is added from your Graveyard to your hand (except during the Damage Step): You can Special Summon it from your hand
Free discard outlets like Putrid Imp or red cards like Faithless Looting can also be used to enable reanimation
Even though these cards are available for a limited time, they are being distributed in a way where so many different people should have access to them

Everything else comes from promo cards or Mythical Island , which only has one pack type
