I played in a Magic: Battle For Zendikar sealed yesterday and it was... Crazyballs. I don't really care about this set, I just want a few copies of each Blighted land and a few copies of Greenwarden Of Murasa, but my roommate likes it a lot and had to work, so he paid for me to play.
Right out of the box I opened the prerelease Ulamog. So that alone was basically his money back. First pack, pulled an expedition (Blood Crypt). Next couple packs pulled some junk rares and two multilands, then last pack I pulled a second expedition (Breeding Pool). I genuinely did not know that was possible. Out of 18 players those were the only expeditions pulled, and I got both.
I did okay in the event. Placed just above half, got two more packs containing a third multiland. I made a kind of dumb blue/green mana ramp deck to try to play with the Ulamog I opened, but it only worked once for the whole event in a game I was winning anyway. Should have played blue/black, but I don't care, my pulls were incredible so if I had done much better it would have just been mean. Too bad I don't get to sell the cards myself, but I know roommate is buying a PS4 with the money from them, so that means I don't have to buy it when Persona 5 comes out.
As for the actual set itself, I don't understand it at all. Much of the metagame seems to be "did you pull a couple of the allies that make allies actually matter?", but beyond that I can't figure out the archetypes. Ramp isn't really a thing, but maybe it's supposed to cap out at seven drops or something. Converge makes no sense to me in sealed, since there doesn't seem to be much support for it. This is a weird, weird set, but then again I didn't really understand Khans until someone explained it to me in context of the whole block like a year later.
