Quote from EvilferretI find the reasoning here problematic. It seems to be something like this:
While it's true that black has historically had the most competitive-viable enchantments (Bitterblossom, Necropotence, Phyrexian Arena, Recurring Nightmare etc)
Black already has a number of nice competitive enchantments. Look at red, blue, green. Yes, they have a few nice ones (Survival of the Fittest, Propaganda, Sulfuric Vortex, etc) but these colors have had their design space for enchantments explored a lot less than white or black.
In black, what are we going to do? Something that's already been done most likely - Lose some life for some sort of card advantage. In fact, spoiler alert, this is the black card that we would end up with.
No one's going to want to look at new design space (Unless wizards forces us into it), because the current design space for black enchantments works well and generates competitive cards.
Whatever we vote on likely won't be anything new and innovative, just some run-of-the-mill black ability stuck onto an enchantment with some triggering condition.
If you're designing a red enchantment or a blue enchantment or a green enchantment you have way more options and a much better chance to see something new and innovative, rather than a "Hurr hurr, black card advantage enchantment"

Also, I wonder if there could be crossover from the MTGS YMTC to the Wizards one. I was most impressed with the green Oblivion Ring variant that turned it into a Forest. I'm going green to support a playable green removal spell, or another example of doing somethign another color does in a green way instead. Unlikely to happen as YMTC will likely be a Rare and Patrick O'Blivion Ring (it's funny because Irish and green...don't hate me) would likely be Uncommon.
At least it will likely be a big-mana-green-EDH-friendly card.
