lol - you'd think so, but I built a legacy manaless dredge deck that was pretty sick, and the guy I play with most just put together a graveyard-hate deck after a few games.  I deserved it, I guess.  But yeah, this one will be pretty slow and grindy, I imagine.  Luckily, I get bored of a deck pretty fast if I feel like it's no fun (for everyone).

I'm still in the early stages of this thing; it's a "cheap" version of real legacy land decks.  I've just gotten it to a list that I'm ready to build, and I'll start playing it against real people soon, I hope.  So to answer your question: I assume that a fast enough aggro deck could kill it, but it has some pretty good combos that can be set up.  It's a toolbox deck, with a lot of library searching and graveyard recursion.  It can play pretty differently depending on the opponent.  Strip mines, life from the loam, and manabond let you clear your opponent's lands, mazes will slow down most creature-based decks, and academy ruins + mindslaver can give you a lock.  Dark depths + thespian's stage quickly gives you a 20/20 indestructible flyer.  Gifts ungiven and intuition let you grab life from the loam + utility lands, so you'll get it all back no matter what your opponent puts in the graveyard.  The cycling lands give you lots of card draw with life from the loam.  Manabond and ensnaring bridge are great.  I really need a crucible of worlds.  I'd like another intuition and an engineered explosives.  I'm excited about trying this out, because there should really be a TON of choices to make every game.
