This means all the cards in the pack will range from Double Rare to Crown Rare
Lets be clear on what I mean with colorless
unfortunately, this monster is not a starter, as it can only be Summoned while you control Temple of the Kings, a card it usually searches, or Treasures, which becomes Temple while in a Field Zone
Channel and Sneak Attack don't have similar rules text, for example, but they overlap in their ability to do broken things with big colorless creatures, so you might pick up a Sneak Attack to support your early-pick Channel, and then prioritize the legendary Eldrazi creatures, Blightsteel Colossus, and Sundering Titan over a card like Karn Liberated, which only works with the Channel plan
This immediately reduces the cards scope for impact
