70% of the time thats pretty good. i could see that being that doom is control. i think with my doom deck i've seen 8 or 9 about 2 out of 7 games. on average for me though i win with doom on turn 7 with Namor (Sub-mariner).

my F4 deck wins on turn 6 a lot because of Hulk, sometimes on turn 7. it depends what i draw.

I run Doomabomber so turn 7 is the turn I blow up the world. Turn 8-9 is where I start to beat my opponents head in.

I generally don't pack so many 1 costs. They're not so important, unless they're Vulture or Destiny. :)

But every formula is a valid opinion.

Decks have run anywhere from 22 to about 45 characters, but generally decks will have 30-36 characters. It all depends on what affiliation you have because each has some kind of tutor(search)/filter/draw capabilities.

And it's always good to be prepared to go to 8 or 9th turn.
