It's been known since last month that there's going to only be one Event Deck produced per set starting with Dragon's Maze. However, a piece of sales solicitation for Dragon's Maze released by Wizards of the Coast sheds even more light on the Event Deck situation: Specifically, that to compensate for the lack of a second deck choice, the usual seven rares per deck are, at least for now, being bumped up to ten.
On the surface, this seems like a pretty blatant ploy by the people who run Magic to try and increase sales for a faltering product. The Event Decks, while well-tuned enough to bring to sanctioned tournaments and often full of quite good cards, simply haven't been selling well. The move to one deck per set rather than two has been interpreted as a sign that they'll be phased out (never to phase back in, not even during their controller's next untap step) for good.
The fact that there are now exactly ten rares, rather than, say, nine or twelve, might be significant as well. There's no evidence pointing to any particular color combination being the colors featured in the Dragon's Maze Event Deck, but coming at the tail end of a guild-related block, it'd be unfair to be only bicolor and represent only one guild. In all honesty, this might well be the first-ever five-color Event Deck, with one rare for each of the guilds.
What do you think about the deck composition change? Will this be a lasting alteration, and do the Event Decks have any future at all? Let me know in the comments.
