With 15 immediately playable cards out of 50, I would have gone with terribly inconsistent rather than just inconsistent. Furthermore, only Muck, Rip off Der Heads and the Villages will increase your draw, so once you're in a hole, it can take a long time to get out of it. The key cards are Muck and End Times, and ironically, you don't want to have both of them in your starting hand.
Without event recursion, such a focused deck is fragile against discards and milling, and very vulnerable to targeted hand discard (Caught the Scent or Gaze of Nagash). High Elves should win fairly consistently, since a single Mage of Loec will break your only plan. Add two quests and there is just no way at all you can win. And this is even without the help of High Elves Disdain or the Learned Mage (a pretty nice combo breaker in general).
When playing against End Times in more balanced decks, you've already mentioned Pleasure Cults as a big stumbling block. Orcs and Chaos will have a harder time to directly interfere with End Times, but at least Orcs have a chance to weather things out with Get Outta my Way. And all Destruction factions can use Drakenhof Castle or Mannfred von Carstein to increase the price of End Times, even as a reaction - ideally, it's not just precluded, but even canceled.
Apart from the High Elves, Order will usually have to weather it out, but at least the Dwarves should be good as this - My Life for the Hold or Rune of Valaya will tide you over for a round, and if you have a Dwarf Ranger and a Master Rune of Spite available, a lot of those big baddies will crumble surprisingly quick. And all of these are key cards anyway - it's not as though you'd need to put them in just against End Times.
So unless I'm completely missing something, this is a novelty deck, and I'd gauge it's success in your tourney to be a mixture of surprise effect and luck of the draw.
Edit: I initially missed the Rip Off, which does of cause add some options. On the other hand, it's such a powerful and typical Ork opening that most everybody will and should be somewhat prepared for it (Long Winter, Called Back, Demolition, ...). Replacing the Villages with Remote Monasteries would make it noticably more dangerous, I think.
