I think we all agree to play Ecology Experts into Trees here, which is a good start.
Playing Helion to push the parameters gives you a better chance if it’s an opponent and in an “engine” game with multiple science tags, card draw, etc.
Playing Tarsis will give you a better chance if it’s an opponent and also in a terraforming-focused game with Ecoline or something like that.
Against a weak player, I would take Helion 100% of the time. Against a player of your level, I think I’d take Helion as well, but it’s more debatable.
In the end, I’m taking roughly the same hand as dessp7, with Artificial Photosynthesis and Carbonate Processing added to play them in generation 2, I think.
Conclusion for me: Helion + Mohole + Eco Experts (into Trees), Deimos + Trees + GHG + Artificial Photosynthesis + Carbonate Processing .
