Moria Marauder, although a Goblin, has Orc (and Goblin) tribal support since whenever an Orc (or Goblin) deals combat damage to a player, we can exile the top card of our library and play that card this turn
Some of the rogue and lower-tier Divining Top decks are probably going to use these as replacements, which should cause some low but fairly sustainable growth
Note the sealed premium is not uniform it tracks how much of a sets demand is shelf-collector demand and prices move
At first glance, I thought it was just another three-mana draw two in blue
There are still plenty of targets for it, so no reason not to play it
So, the Set Booster has less overall commons and uncommons than a Draft Booster, but we believe we've balanced them to what is more optimal to the players (not creating cards they want to ignore so quickly) to allow us to put other things in the booster that would be more exciting and impactful
