Does your own demand for a card create the value, or is that value better determined by some other metric
For just the main set card of any rarity youre at 0.76% to hit any foil mythic and 4.6% to get a foil rare in a Set Booster, and for a Draft Booster its 0.25% for any foil mythic and 1.5% for any foil rare
In a typical Commander deck that doesn't build around her, that will likely be: Land - pretty sure Creature - likely Sorcery or Instant - at least one, maybe both Then maybe an artifact, enchantment or planeswalker That means you could easily draw four or five cards in a typical 10 set and choose the best one for the situation, like the best land your reveal
