Blue Credit: Wizards of the Coast Defabricate BPhillipYork: The ability to counter an activated or triggered ability might save this, you can use it to a stop a Thoracle win in it's tracks, which might just get you there
Legion's Initiative This is my sleeper pick for the set even though a ten dollar sleeper is a stretch
Humble the Brute: too heavy for the benefit, but it could be useful in limited or in Standard with a lack of other cards in white with a similar effect
Minas Tirith : Single white mana producing land, able to come into play untapped if you control a legendary creature
The drawbacks are the limited choices of packets, the cards from Wizards-selected recent sets and the only reward for this event is a randomized individual card
Have interesting cards to discard, madness, flashback, etc
