Divine Intervention

So, Darkness was pretty bad, but this one really takes the cake. What the hell do I do with this?

Almost no one, least of all Wizards, likes tied games. The only person who enjoys ending a long, drawn-out slugfest in a draw is a troll. It's a nightmare for TOs because the card turns nearly any losing situation into a draw, while making winnable games go into "stupid long" territory.

In short, this card is the assbastard's Platinum Angel.

... which gives me an idea.

There you go. It's worse than Platinum Angel -- it can't swing and it's harder to cheat in -- but it's easier to protect. It's patently unfair for kitchen-table Magic, but it's too expensive for most Standard seasons (note that I said most, but even where it would be relevant, I'm not sympathetic to a deck that just loses to "an enchantment.") I'm not entirely sold on this being a white card, but I can't make a solid argument for the effect in any color. With white, at least you have the "white makes arbitrary rules" flavor, even though those rules are supposed to be theoretically symmetrical (Rule of Law, etc.).

I could see it in black with a drawback -- an enters-the-battlefield trigger to set your life to 0, or a leaves-the-battlefield trigger to exile your library, for example -- and I could see something like it in red, justified by the color's bloody-mindedness. (Maybe something that made you tougher to target or damage when the opponent had the upper hand, like more creatures or life points.) Blue doesn't get a pass -- what, drawing, flying, flash and counters weren't enough? -- and green would probably just be happier with a bigger dude with trample. (Why durdle when you can just win?)
