Because its not specifically called out in WotCs terms and agreement, third parties arent technically prevented from selling Arena codes for special products, decks, or individual cards
It is a good thing in general to have but for certain kinds of cards, like these two, and like Shatter, it makes all the difference
It's good, but it's six mana and there are cheaper artifacts I can run to help me out with my tribe of choice

While using your turn 2 to scry was very strong, especially after a turn 1 Thoughtseize or Despise, not having either a discard spell or a Temple was disastrous, especially on the draw
It's not all about being the best at drawing a bunch of cards all at once, just stick to your game plan and Green has your back.
