Magic The Gathering Discard Deck Help?

take away those 4 bloodstained mires. you realy dont need them at all. A deck should around 20-25 land, about 1/3 of your deck should be lands. If you follow that rule(which you do), then you shouldnteed those 4 bloodstained mires. You can keep one or two i guess, but i dont use mine at all.
