This deck is pretty good but it gets mana screwed often. When it's not mana screwed it owns, which isn't that much. All my other 3 color edh's have the same mana curve and they all do great most of the time. Any suggestions on this deck.
Too much or not enough mana?
99 cards. So in the average deck 1/3 land should work, which would be 33 land. I run 36 plus creatures that make mana and reduce mana cost. Yet I never have enough mana to cast dragons. I have a naya edh that's more mana costly and run less lands and less mana producing creatures. It runs just fine.
1/3rd? Usually 2/5ths is what is recommended (40%). my EDH decks usually run ~38 lands, and always perform quite well. Less works, but I wouldn't go below 34-35 lands, and that's really pushing it.
Side-thought: I would really recommend some thing like {Rampant Growth} or {Cultivate} in any EDH deck that includes green. Being able to fix mana colors is a godsend, imo
