Ive played every one of these cards in Commander, and while only some of them see consistent play in my decks today, all of them can bring more out of your mana base in a white Commander deck
The contents are as follows: Common (6) Uncommon (3) Rare, Super Rare, or Legendary (2) Foil (1) Each pack comes with a foil card, which can be of any rarity
Both Scythe (with first effect, of course) and Immortality feel a little too strong: I would restrict one to once per turn and the other to twice per turn, depending on your thoughts over which should be nerfed more
You may choose to discard your hand even if your hand contains zero cards
So if you change 'Summoned Skull' to Level 3, and Summon it, it can attack even if 'Gravity Bind' is active
Storm would dabble in Aria of Flame, the card Ensnaring Bridge and the entire deck Lantern Control existed
