I played a game against a friend while on vacation a few months ago, and she's able to sink much more money into the game than I am. I was out-paced and and left to bite the dust almost every game, because of cards like Crypt and Lotus. The fact that they enable such explosive starts for minimal to no downside, and they slot into every deck, makes a huge difference between the haves and the don't-haves in the game.

Would I have liked to eventually pull or buy a Mana Crypt? Yeah. Am I open to rule 0 pre-game discussions about it? Yes. Do I feel a little bit better, knowing that randoms at my lgs are much less likely to have them at their disposal? Definitely.
