We have been hosting a Netrunner tournament on the 2nd Saturday of each month at 12:00 for a while now, at:

Manaleak.com
TCG Tournament Centre
32 Broad Street
Worcester
WR1 3NH
United Kingdom

The tournament starts at 12:00, but we tend to all go for a late breakfast together at a diner up the road at around 10:30 (we all meet at the shop first). Anyone interested is welcome to drop by!

Prizes tend to be either a split of the entry fees (£5 per player), or something from the tournament pack (if available). The atmosphere is very relaxed, and we tend to be happy to "do deals" to get new players involved, so if someone wanted to enter the tournament with a starter deck (to see if competitive play is something they are interested in), the TO would likely waive the entry fee for that player.
