It's pretty obvious that decks for the other three Gatecrash guilds will be included in the expansion. And, like the Return to Ravnica expansion, they probably won't give us any clues about those guilds' new mechanics or include any new cards. Still, new decks to play with are always a good thing.
How about "You may discard your hand, pay 5 life, rip this card, remove 3 digits from any number of target fingers you control, and concede at the end of the next end step rather than pay It Will Go Through!!'s mana cost.
The game and expansion are cheap as dirt, it's hard to argue that it's not all worth it. At the end of the day, it's way cheaper than many video games on the market. Video game pricing is slowly and slowly starting to make more sense.
So it's 240 Microsoft Points ($3), compared to the $5 I just paid for the other Return to Ravnica guild decks. A bit disappointing, would have made more sense at $2, but like I said, I'll be getting it either way. I'd probably have paid $3 just for the Boros deck.
