For posterity, here’s an all amphibian trash person spam list that I slapped together yesterday. The goal was to take only Amphibian units but also go obnoxiously hard:
Riverguard Dambuster Horde - Brew of Sharpness, Poison Frogs
Treeleaper Dambuster Regiment
Treeleaper Dambuster Regiment
Treeleaper Dambuster Regiment
Treeleaper Dambuster Regiment
Treeleaper Dambuster Regiment
Treeleaper Dambuster Regiment
Riverguard Regiment - Poison Frogs
Riverguard Regiment - Poison Frogs
Riverguard Regiment - Poison Frogs
Riverguard Arbalest
Riverguard Sentinel - Poison Frogs
Riverguard Sentinel
Riverguard Sentinel
2300 14(25)
All flying, almost all nimble, loads of shooting. The Arbalest could be a Riverguard troop in the same chaff roll, but I went with the cooler mini with a shooting attak and slightly better Nv. The height difference is a mixed bag - better for shooting, worse for hiding with a token.
I was going to put the Periscope on that one Sentinel, just to be cheeky (and for engaging over hills), but RAW I’m not sure it works. Leaper sets its height to 3, and I’m not sure if the Periscope’s +1 Ht modifies that to 4 or just gets reset to 3, as Leaper specifies a number It really doesn’t matter, so another brutal-on-demand it is.
EDIT: I’m still surprised at the De 3+ on the Treebusters, it’s lower than all of the other large cav shooting flying regiments that have defined the meta in the last years (which are 4+). Treebusters don’t feel like they have a huge leg up on their counterparts, apart from the 22" effective range on their P(1) shooting, nor do the models seem to justify it. Even logically, the Riverbuster is a De 4+ frog on a toad, for De 5+. Wouldn’t the Treebuster be a De 3+ frog on a toad, for De 4+?
