I'm in a contest, and the goal is to make a card that costs at least 7 mana. I've narrowed it down to three prospects, and I want your opinions on which one is best before I send in my submission. Remember that these cards will be judged on Balance, Flavor, and Creativity. That means that "broken" does not equal "good", and "safe, same old crap" doesn't either. Dimensional Warp 4WWB Sorcery Remove all creatures from the game. During each player's upkeep, that player returns a creature removed from the game in this way to play and loses life equal to its casting cost. ----- Temporal Fluctuations 5UU Enchantment You may play spells whenever you could play an instant. Opponents may play instants and abilities only when they could play a sorcery. ----- Dazzling Aura 5WU Enchant Creature Enchanted creature gets +2/+2, is unblockable, and has, "Whenever this creature deals combat damage to a player, you may gain control of target creature that player controls."
