This is a thought, in no way do I believe it’s probable. However, a Spartan stabbing another in the gut causing said Spartan to bend over for the setup would be amazing, especially to see the stunner happen!!! It would be more satisfying than the lawn dart. I wouldn’t care if it had to be a mythic legendary card, it would be worth it.
Some armor and helmet possibilities that I would like to see include:
Noble 6 default standard from Halo Reach
Rogue helmet from Halo 3
Original Recon helmet and armor from Halo 3
Mark V helmet and armor from Halo CE Anniversary
