While at MagicCon Vegas in late September this year, I spoke with Mike Turian, product architect for Magic (though his role while M21 was in design was principal product designer, according to his LinkedIn), and he confirmed that for M21 the design for showcase cards was intended to keep the text boxes clean and uncluttered, kind of like you would see in simple but powerful spells with only a few words on them, like Wrath of God or Counterspell
cards on your field is at least 2 less than the number on your opponent's field, give this card in your hand 3 cost
If you are a collector of PSA holders that look good for your collection, how about this opportunity
If youre playing a red deck, Dockside Extortionist is a powerful card to consider since being able to ramp up equal to the total number of artifacts and enchantments your opponents own can put you massively ahead of your opponents
