MTG Duel of the Planeswalkers 2013

[Pinky]

The justification of those reforms assumes that your player-base reaches a critical mass, stagnates, and appealing to a larger audience is no longer profitable for the health of the game.

If you look at the last few sets of MTG, they're actually in the process of pushing more towards the luck end of luck/skill spectrum. They've gotten rid of mechanics like Scry, they're scaling back the power-level of cards pretty significantly, they're adding things that work with luck (Innistrad's emphasis on the graveyard as a resource, I would argue, emphases luck) and they're making cards that are simple, but can all work well together (Soulbond, "flicker" effects, exalted, etc.).

This trend will probably continue for a couple more sets before things get "overpowered" again. They're appealing to a wider audience by trying to scale back the amount of skill "required" to have fun playing the game.

If spells' power levels are being flattened, that's a move away from luck -- reduce variable, reduce random luck. Removing some effects and making others more common has the same effect, although removing scry is obviously one instance of less control. (its been removed before, though. it'l be back later)
