Can we not buff the Boas to be something more thematic? They certainly aren’t the fastest creatures available, but for that “Snake Strike” effect of real ambush predators they ought to have one Instant attack available to them.
And a little more HP for each of them. Make them at least marginally more relevant.
*Disclaimer: I have no experience with Spinoconstrictor. Maybe that one’s well-represented, I have no idea.
