I will also back up the awesomness of Jinxed Idol. I'm considering Mogis as a grindy predominatly black card, that can randomly attack for 7.
Yeah. That makes no sense at all. You'll run Elvish Mystic, Llanowar Elves, and Fyndhorn Elves - all identical cards in everything except name - but suggesting you run 4 gravecrawlers is somehow not acceptable? What? A couple guys were going so far as to say that anyone running multiples wasn't cubing - they were running a custom format entirely so different that calling it a cube would cause confusion. These same guys running three functional copies of Llanowar elves mind you (who would happily run a functional reprint of gravecrawler if it was printed). Hypocrisy at its finest.
