I like seeing these competitive guides because BTD6 Fenxi and Punji BTD6 already really good non-competitive guides. There's very few good competitive guides. You're my favorite person for competitive guides.
i think you can skip monkeynomics, try just buying rod and you should have enough money on t4. On t4, you want to remove the shield layer of the first skull and then just focus rod on the bloons so rounds end as quickly as possible. Then buy the paragon on around r109
