I play MTG and decided that I'm gunna make alternate art for my Goblin deck since its in its final and finest form. But, saying I'll draw art for 100 cards sounds like a perfect way to lose interest and motivation before even starting.. 

So here's the rules for each piece of art.

I set a 3 minute timer for line work. That's it, what ever I can get in that time is all I get.

Then I put away the card, and do not refer back to it at any point while I quickly add color to my drawing, takes about 2 minutes each.

So far these are my five minute alternative art cards in all of there horrible glory. I love them so far. Lol
