Starting with the Alara block, booster packs for both Core Sets and expansions began to contain 1 land, 10 commons, 3 uncommons, either 1 rare (7/8 chance) or 1 mythic rare (1/8 chance), and either a tip card (which explains the new rules in the set, such as exalted in the Alara Block or Infect in the Scars of Mirrodin Block) or a token (which is of a type produced by a card in the set)
Game-winning combos The enchantment Sphere Grid is a card you will want to get out early
It can swing, block, and pretty much get down tonight
Torrent Sculptor is rarely a card you want to play and serves mostly to add a color to the EDH requirements for playing this card
