Had a bit of a go at this, properly, and it's mostly competitive though weakest against NG. Which is a shame, because 90%+ of decks seem to be some kind of NG meta.
It's basically about increasing the chance of drawing the right cards, so Foglet, WHRider, Renew, Royal Decree and the summon high/low are handy, as well as Penetant. For R1 it's some consume pace and low deathwish, Barghast is a bit OP, Kayran, Frightener. Then your standard DW units, Manticore, Miruna and then the finishing stuff, Troll, Caranthir, Ge'els, Wraiths and Glustyworp. Won with 2 x Ge'els and a last play of a 40 point Glusty. But I felt kinda dirty doing it.
If you face it, push and push R1, you need to at least go second R3 or better still get the card/turn count below 6 in the final round. have a reset card (Artifact is good value at 5 prov), something to purify and you should be ok. Or just play as NG and use any one of dozens of mechanics to kill whatever you want (Vilg, Invocation, Seize, Poison).
EDIT: Great Dandelion Show Special:
Picture the scene - me (Noonwraith) vs opponent (Monsters; Gernichora). So my opponent seems to have a fairly straightforward deck of insectoids, R1 is won by the usual dynamic of boost (bone talisman, arachas queen), but only after my opponent has played Geralt Yrden. I'm not really following why an insect deck would carry Geralt, but ok.
R2 it's a dry-pass so I stick a bronze down and into R3 we go. Remember, the oppo cards are insectoid and we are all aware of the better cards within that deck. So I've got a decision here - do I go for the rats thing and try to out-maneouver a potential Glusty play? Let's do it, I've got renew, so I play Penetant in case of Dive, then onto Defender. knowing that any MO - Insect deck is very unlikely to have any way of dealing with it. I'm thinking this is probably a Glusty straight shoot out. Nope, apparently not. So my opponents next card? Purifying vampire. Riiiiight. Makes complete sense in this deck. Not.
So anyway I'm in a bit of a bind because the oppo can always get a 1 unit on the board, so I Caranthir into Ge'els, then repeat to at least get a couple on the board. That'll work, right? Nope. Opponent then plays Yennefer to do 2 damage to everything, both Ge'els gone. Little more understandable card, I suppose. So I play my final Ge'els and my opponent then produces Weavess: Incantation to play Parasite and kill my final Ge'els. So I'm out of Ge'els, opponent had en answer, every time, to this exact problem. Unperturbed (and visibly laughing at this point) I get a few DW and consume cards down to spawn some Noon-rats as a result, there's about 8 rats or so in play now and I have my renew ready to Glusty myself to some decent point. Before I get the chance, however....and this is the big reveal....the opponent plays bloody MORVUDD!!!!!!
I mean come on!! Insect deck, with no beasts, and the opponent has Morvudd just in case of Noonwraiths?!?!?!?! With no thinning my opponent got Yrden, Yen, Weavess and just happened to have Morvudd. If anybody is seriously telling me there's no sort of rigging going on, then they're mental. You couldn't make it up and in this example it didn't even make a lick of sense. And I'm talking about level 8 match-up here; the one time I don't face NG seize I face, specifically, the anti-noonwraith deck. What are the odds. Seriously. What are they?!
