Does this sound like you, con-goers? Tired of using flimsy scraps of paper with numbers written on them to remember how brutally you've savaged your opponent's card-beasts? The Trading Card Center's got your back, and just put these nifty new damage counters on the shelves!
Oh man, middle school and high school flashbacks with Magic: The Gathering...LOL good times.
