It has protection from red, which means that a card like Pyroclasm would have its damage prevented, the Knight cant be enchanted by Aspect of Manticore or equipped with Embercleave, it cant be blocked by any red creatures, and it cant be targeted by spells like Academic Dispute
It even shuts down artifacts, meaning you can use it to stop something like an Energy Refractor dead in its tracks
Tips for the Secondary Market: Always check seller ratings and reviews
