As Blitzer noted, you need a 40 card list, so if you're too uncertain about what to cut (I always am with my decks), perhaps my outside perspective might help. So here are my thoughts as I go down your list on what is perhaps not essential to include in the deck. I know cutting cards isn't always easy, but hopefully this can help you refine what you're looking for in the deck...

I'd say cut the tailspins...and the karikaris...it's just not that good if you're not dedicating the deck to red/green, and rainbow red/green in particular. Similarly Death March is best in a deck with reliable darkness in the graveyard. It's looking like you've just not enough darkness to make that a worthwhile inclusion, particularly if you cut the self-mill cards, which I would recommend you do. And then Zamaru and Crowd Mayfly are definitely not good fits for this deck which also features a Civilization breaker and Space Chargers--you have to pick a lane and go with it: either go for 5civ or go for particular-civ-centric effects, but definitely try to avoid mixing them. The Civ Breaker is quite expensive and as long as we're trimming cards, I'd say he's maybe not the best fit since it's likely going to be harder for you to get a high civ count after making cuts. I know you've got Courtney, but perhaps it's a bit risky to hinge the deck on that card hitting and staying in play? She also wouldn't help your space chargers, if I'm not mistaken, since they don't enter the manazone as all-civ, only once they've already landed. With that in mind, I'd say watch out for the space chargers and only keep the ones that (really, really) work (well) with your deck post-cuts. Sundrop Armor, Fairy Scoop, Drill Squall, and THE FINAL (definitely) aren't worth it, I'd say...Darts is not too reliable to cast your monster Invincible spells, so maybe cut that whole package? I'd also cut Poseidon if your space charge number is too low after cuts. Nexus Charger is way too expensive, I'd say. You've got way more impressive things to do at such a high mana count, and this charger is probably more of a burden than aide. Aldebaran is an interesting card. It excels in a green-heavy deck, but it's still a threat without. That's the kind of space charger you should look into: stuff that can still be brutal even without the charge. That being said, you definitely want to make it as efficient as possible, so keep him for the Tbreaker power, but definitely make sure there's a good chunk of green for him to associate with, otherwise you can't even cast him! I'd say Perfect Earth is better for you than Greatest Earth since it's cheaper and thus easier to cast. It's a back breaker that you can't just throw it into mana so it doesn't lay dead and uncastable in your hand, but if you're heavy in space chargers, there's at least some benefit to it hitting mana. Even so, it would only activate a space charger once max, so is that really worth it? Probably not, but if you can muster the mana to cast it, it's definitely worth it. So with that in mind, doubling these problems by including both Earths is probably asking for trouble, so if you must include an Earth, make it Perfect, but see where you're at after cuts first. If your slimmer deck can more reliably cast and keep Courtney (and see several Space Chargers in the battle zone), then things are looking Perfect for Earth, but just really think about what you want the deck to do most and do whatever it takes to make that easier to do. Best wishes with editing.
