Sick of your prized trading cards getting knocked around in your bag
It's around #14 or 15 on my list and not in the Top 10 proper, but the ability to force someone to discard, and destroy artifacts and critters with one number is a very precise scalpel that destroys what you need, but tends to leave your own stuff alone
Virtually every creature in the deck generates card advantage in some capacity
That would be fine, were there not two designs of the code card depending on the contents of the rest of the pack
It deals damage equal to its power to each other creature
I like winning, sure, but I also like playing different styles, using different strategies, and showing off different aspects of my deck-building
