Explore the Fallen

ok here is my break down, this is a very obviouse titan ramp deck but the twist i use is of course black over red. i use ob nixilis ability and all the land ramp to do damage (very simple)but it has alot of twist to do massive damage the turn after ob hits the field. so lets say that ob hits the field turn four or five. then next turn you lay down a sac land -3 life, pop the sac land and fetch another -3 life then play explore throw down another sac land -3 life pop that sac land again -3 life again. so your opponent lost 12 life and od is a 17 17 beat stick. i try not to play any of my explore and as few sac lands as i can untill ob hits the field so that i almost always have one if not two explore in my hand and at least one sac land. the other way to do it is turn 4 or five play ob, next turn primeval titan they loose 6 life go after two sac lands and pop them and there goes another 12 life so i mean its not real hard to figure out that part of the deck. or i have even sat with khalni in play with three counters until ob got put out and them hit them for 18 life one turn after he came into play. if that doesnt work just side in the baloth and grave titans and beat them to death with tokens lol.
