Labrynth

This deck came out of my interest in making Lab work in a slower format where they have been understandably heavily nerfed - without the hits to Big Welcome, Welcome and Lady, this deck would have absolutely dominated Genesys to a frankly miserable degree. 

Dracotail Horn triggering Lovely Lab is very cool, plus the 4 card package of the Dracotail traps are a great addition to the Lab normal trap entourage - with an attack position bounce, a spell negate which comes in very handy both on the field and copied with rollback to protect your backrow and a double DD crow GY banish. 

Testing with a small paleo package to send rollback or other GY targets, as well as Leancholia to return Big Welcome and Rollback. The ED Paleos are probably unlikely to be summoned but can be used if you ever get two Paleos on field

Lady at 1 is essential and there was only room for 1 Welcome trap, so Big Welcome was chosen as well as Farewelcome as a secondary target. The remaining points were unfortunately increased so we can only use 2 trap holic but have replaced the third one with a trap trick, and rollback now also costs 7. because of this only 2 daruma karma cannon can be fit in. 

I still think that if you are a good Lab player this is a very strong deck in a format with no lightning storm, no duster or heavy storm (MOSTLY) and evenly matched also being 30 for a playset so mostly you'll just be dealing with twin twisters and cosmic which are less onerous. 

Enigmaster Packbit is in as a 2900 synchro send for Ulti Slayer or Dogmatika Punishment if they have a high attack monster. Everything else is relatively interchangeable - I like Gordian Slicer and Ulti Slayer as going second cards to reset the gamestate and allow you pop off 

Any queries let me know - I am far from a 'good' Lab player but have played trap decks on and off for 2.5 years since returning to the game (more Paleo than lab but a lot of Lab on Master duel too!) but I think this list makes sense but will edit as I play the format more
