Hey there, if you've just searched the web for "Yugioh Lancaster UK", then you should be seeing this result and follow the link if you're interested in playing Yu-Gi-Oh! TCG in Lancaster.
Sorry, for the top bit, but after noticing my own page on Google and as it shows only the first sentence, I had to get that out of the way first. I'm Nick Green, a graduate of Lancaster University, and a RC-1 certified judge (so I'm not too important). I also run the Facebook group "Lancaster Yu-Gi-Oh! Duelists" and after a couple of years of being very unofficial, we are now running sessions every Sunday from 5pm at Juicafe, with full support and backing from Konami! If you're in Lancaster and looking to duel in somewhere closer than Blackpool, then head on over to the facebook page: 
Aside from that, I've ran many decks including Glad Beast, Blackwing, Psychic, Synchro, LightSworn, Machina, Six Sam, Inzektor, X-Saber and Gravekeepers. I've won a few hobby leagues, Blackpool's Starstrike Blast Sneak Peak, and placed 148th in YCS Sheffield.
I also wrote the Ronintoadin Featured Card article that was on the front page of the the wiki for a while, so please leave a message on my talk page if you'd like to talk about it or give me feedback on it.
