Probably the best deck under $2.

This should not work.

TaquitoCourt But it does... 11.7% of the time ; )

I calculated the actual percent of time you'd get the crusader in any of your hands (including mulligans) without reaching Fatal Frenzy too soon. The total came up to be about 33% of the time. I had the work all typed out in a comment, but it failed to post and I didn't want to do it all over again so you'll have to take my word for it.

P.S. My calculations included the chances that you'd get to a hand size, keep it, and not draw fatal frenzy, adjusting the calculation based on the size of the deck. I then added the chances of a successful hand and deck arrangement before the game begins (the chances that you'd get to a hand size, keep it, and win). I also acknowledged that you would mulligan whenever you had Fatal Frenzy in your hand, even if you had the crusader as well. I only looked at scenarios that won in 4 turns and assumed the opponent's life total remained at 20 and they didn't have any creatures to block with, which would require more lands before Fatal Frenzy. to overpower it enough to kill the player.

P.P.S. I haven't done the calculations, but I think Fling would do better. You don't have to worry if it's in your hand, because you can stop the crusader's chain as soon as he gets big enough. If you reach it too soon, you can just play it next turn. It does require more lands to win on turn 4, but you can still win if it is too close to the top. In addition, you don't have to worry about your opponent's creatures absorbing some of the damage.

zebeg, Can you interrupt the first ability of countryside crusher with an instant speed Fling? Based on the second ruling from the wizards, "Each time you put a land card into your graveyard with the first ability, the second ability will trigger. Those triggers wait to be put onto the stack until the first ability has completely finished resolving." it would seem as though you can't play Fling once the crusher gets big enough. You'd simply mill yourself out

Yes. When enough triggers have resolved to make Fling do lethal, put it on the stack. When it resolves, sacrifice the crushed to do lethal

1st playtest and opened 6 Mountain and Countryside Crusher then milled 50 Mountain from my deck on turn 4, drew Fatal Frenzy as the last card in my deck, soo... Good deck!

Jorone Well played sir!

Simply beautiful. Much applause from me. +1

Technically this deck works more like 36% of the time, because you can mulligan until you hit a Countryside Crusher
