[Deck] BGR control

[KDenz81]

This is an old LD deck of mine that I turned into something a bit more naughty.  It can now take out Artifacts, Creatures, Enchantments, and Lands and still beat down my opponent.

A friend of mine has actually outlawed me from playing this deck at his house.  I blow up everything, and I mean everything he plays.  If he doesn't counter my threats even more threats get through.  If he can't counter enough of my stuff he usually concedes.

In reading this decklist, I felt that you have too much artifact/enchantment/creature hate.  You would probably be better off focusing more on the mana denial plan.  You could also consider cutting down to 2 colors (RG) for consistency.  The beauty of using LD is that you don't need to worry about high-CC threats which you can't deal with using burn spells.  Thus, red is all you need for removal.  For example (this list is really rough but I'm sure you get the point):
4 BoP / werebear (the bear beats as well as adds mana)
4 eternal witness (sooooo good)
4 argothian wurm
4 elvish spirit guide
2 gorilla shaman / hull breach
2 genesis
4 avalanche riders
4 ice storm / pillage
4 stone rain
4 lightning bolt
2 hull breach
4 wasteland
4 taiga
4 wooded foothills
2 mountain
4 forest
1 strip mine
1 sol ring
1 black lotus
1 mox emerald
1 mox ruby
1 lotus petal

The Deck list you posted Covetous is mostly what this deck was like before I modified it.  It was just a red green ld deck.  Since Crucible was printed, it allows easier land distruction with Wasteland and Stripmine.  

My build has 8 ld spells, 3 lands with strip effects, and 4 Argothian Wurms where an opponent chooses to sac a land.

This leaves me room to deal with Artifacts, Creatures, and Enchantments.  Most LD spells cost 3 and Chalice for 3 against a straight up LD deck owns.  This deck has threats to take out any number of threats your opponents put into play.
