last time i played was when i was a kid, and i stopped a bit after pendulum summons came out. i want to get back into playing, i have probably close to 1k random misc cards but i assume most of them are completely useless. i'm looking for a deck that i can learn with and one that's strong enough to compete at a LGS without spending $500 for a deck. one of my coworkers plays a branded tearlaments deck which is apparently pretty strong, so i'd like something that can compete with that as well. any suggestions?
