I do enjoy a lot of these permanents, as a lot of them are pretty awesome; my votes, however, went straight for the popular ones.
QUANTUM PENDULUM
Everyone else has a pendulum; why not the Other/Quantum Tower? Not to mention it could provide an alternative to Nova decks.
WINTER
I can totally see this card getting used a lot; I can't stress enough how badly I've wanted to shut down an opponent's Eternity or Owl's Eye and couldn't do it. This card can go into any type of deck without slowing it down too much, and it deals a good amount of damage for its cost. I like. <3
MAGNET
Poison Trap would have gotten my vote if I felt the Upgraded version wasn't overpowered (neurotoxin = shutting down ANY chance at PC). Magnet, on the other hand, forces the attack unto itself while not creating making every PC card dead to the opponent; I mean, who's going to pack enough Magnets to accomplish something like that anyway? Did I mention the part that it's a perfect fit for Gravity to synergize with other Elements?
SCRYING POOL
I love the concept of being able to discard cards (like the Discard card) and shuffling your deck. I'm not sure how good this card would be for smaller decks, but it would play in a very interesting fashion for larger decks.
Not to mention that being able to see the top/next card in your deck helps to decide whether or not you want to use the ability. It's an aptly-named card with a perfect ability.
