I've been playing for years exclusively online, but I've been slowly building an Ice Barrier deck irl since they're my favorite deck period. What I'm concerned about is a few things:

What do I need to actually bring besides my deck? I've got a mat from the IB Structure deck but from footage I've seen on youtube they don't use them so I don't know if it's usable
Do you need cards that are explicitly tokens? Because Ice Barrier tokens are like 5 bucks each and I don't get paid till next month lmao
What cards are best suited for the Side Deck? I usually go with Board Breakers if I'm forced to go second, but I figured it would be a good idea to ask

Looking to start playing at a locals IRL for the first time, a few questions
