This is the kind of awesome big-mana bomb that I love to play in Commander
If at the beginning of your end step there are more than 8 cards in your graveyard, the enchantment flips and becomes a 4/4 creature with flying and Crew 1, which allows it to become an Artifact creature until end of turn
You get a ready-to-play 60-card Planeswalker Deck and use it to do battle against others participating in Open Dueling, including players participating in the main tournament who are between rounds
You may find that decks composed of cards from the same set may work better together, but the important thing is that if each player has two packs, they can just open, shuffle and play
Then milk value and stall with your midgame until you can close the deal with spiders or Eldrazi or even just too much value and control to lose from your position
