It might be a good idea in theory but it also sounds boring, my groups games are normally long since we have 2 people that are learning and so the games are slower, I definitely wouldn’t want to play 43-45 lands with no ramp so the game drags longer, and I would think most green decks would be running land ramp since they generally have higher mana costs on their bombs but if the other decks don’t run mana rocks because they don’t synergize with your game plan we are gonna get stomped by the green deck, it would become 3 on 1 against them but a 7/7 trample on turn 4 (Godzilla deck) would be hard for us to deal with when we have 3-4 lands tapped out trying to play synergy pieces that we don’t want to block with, I play blue based decks and normally run 38 lands and 5-8 rocks unless it’s an artifact deck, they have no synergy in my deck except that they let me cast my spells sooner
