This. I ran a game against a StD player with a 3 durthu alarielle list, he was using Archaon and a blood thirster for double pile in and attack goodness. Even considering Alarielle needed a 5 for throne of vines, and a subsequent 4 to pop off a woods, because of poor rolls i failed all her spells and spent the rest of the game with 1 wyldwood in my deployment zone and 3 durthus at sub-optimal strength. Archaon piling in and ignoring the charge phase saved him from the stomps and he killed alarielle + 2 Durthus before the General with seek new fruit killed archaon and cleaned up the rest of big threats. However, with the lack of woods and model count I lost heavily via objectives.
I'm tinkering with a list using Alarielle, Durthu, TLA and 6 scythes as a base. Durthu is pretty reliant on not being bracketed , and in games I played with more than 1 , it's weird to say he feels like a glass cannon , at least comparatively to the Kurnoth Hunters. I've been getting much more mileage using him as an assassin rather than an anchor/anvil. In the games without the hunters I found I sorely missed them. A little short on model count , however, the combination above brings 1 auto wyldwood from the ancient, just in case of garbage rolls. Alarielle brings a (semi) reliable turn 1 ToV + Spiteswarm hive combo. This combined with a retreating gyrstrike Durthu and a block of 6 hunters that can all pop out of woods and charge turn 1 on a 6+ seems pretty nasty .
In terms of sideboard , I'm thinking 10 tree revenants for the utility. or 20 dryads if more bodies are needed. Durthu is swingy but he's been my MVP for every game he's been in, the amount of gods and demigods he's killed with 3 strikes of his blade... just to run back 6" to the wyldwoods so now you can't shoot him. Very fun.
