On record, I think the only one-site win decks in LoTR TCG are Uruk-Hai Bomb and Moria Swarm. You either need a ridiculously kick-#$&*@! swarm or a bunch of fierce minions that will kill your Fellowship in one turn.
I will say that there are several well-designed strategies for one-turn kills...if you play Kralik on GCCG, that is how he likes to build a lot of his decks. But the only consistent one-turn kill deck is
![Moria [Moria]](https://lotrtcgdb.com/forums/Smileys/classic/moria.png)
