Polyraptor Polyraptor is a very easy card to break and thus a great mythic to craft for Historic or Timeless
Set pricing rules across channels to maximize profit and stay ahead of market trends
Against late X spells, however, counterspell or bust applies in this format, too
Even with it, it is still a very good card especially with the proliferation of counters these days
Another issue with this is that you can even get these crazy DISCARD cards in your slot, or worse your mythic rare slot: These DISCARD cards are a bit more common, as they have happened over the years in plenty of recent packs of sets, but to get one in a $10 pack is still pretty disheartening
