A packed lunch and something to drink would probably be a good idea, but we will be in the middle of birmingham city centre so there will be places nearby for you to buy stuff if you prefer.
I plan to bring some sleeves to play in, since I pretty much always do. We will only be able to buy sleeves there if a trader is present. Since The Place for Games also sell products as well, I am making an educated guess that they might bring sleeves to sell and other accessories as well.
Another thing that would be useful is some way of recording your hero's and allies life totals. Either dice or some of those glass counters would be ideal for that since the values would be changing frequently in the game. At the worse you could probably use pen & paper for your hero and maybe some coins for the ally's but that can be a bit akward.
Reading the rulebook again its says sealed deck format is a 30 card deck + Hero, with the rest of the cards being the side deck. I'll need to check the release announcements to see if this is correct.
I'm not 100% sure what time I'll be getting to New Street on Saturday as of yet since I know that there is engineering work between Redditch & New Street so I will have to most likely be relying partially on a replacement bus service, but will check the times and post on here once I can make an estimate.
