I had a lot of issues with it and finaly beat it and wanted to let everyone know the best strategy. I tried machinations, UQ, Wielding Steel, Auramancer, etc. No matter what I did they'd overpower me with ridiculously big krovikans. I finaly tried Lilliana, a deck that I hadn't unlocked anything with yet, and didn't really plan to cause I don't like mono black decks. The scheme cards are ridiculous for that deck, I got one that said "Target player chooses himself or others, if he chooses himself he discards 4 cards, if others then they both discard 2. I got that scheme three times in a few turns, which I guess helped a lot lol. Basically I just burned them all down to 0 cards within a few turns and used lilliana's caress to burn them down while doing it. It turned a very hard fight into a very easy fight. Just figured I'd post it in case anyone else had troubles.
I've been having a lot of luck with GW but if I can't beat the three J's after a couple tries then I'm just going to switch to AD. I plan on restarting until I get an Eldrazi in my starting hand then hoping for the scheme that let's me drop it. It'll only be a matter of time until it gets bounced, or worse, Mind Controlled though.
Be careful, some of these are illegal...in Mexico.
