Hey, my aunt is a Math teacher and she started playing Magic when it came to my country (Brazil) when she was in university, so some cards are like 20/30+.

I dont know much of magic, i just played some years ago with some friends and i have this commander deck (last pic), i just know that this cards that I separated are the most interesting, i dont know if i can do some thing with these boxes cause of their state but if some one can help me, i would appreciate, thanks
