One of my friends wants to play Tiny Leaders. I was initially like "ehhhhh", because it's obviously a scam or something, but after reviewing my cards it turns out I have most of the standard "good" stuff to put together a Jeskai deck. I kind of see the appeal now of having a place to get good use out of single expensive cards you happen to have, like Snapcaster Mage or Clique, but are far off from having a playset of. Which I guess Commander also does, but I only ever want to play Duel Commander, because there are far better games about interplayer politics I could play instead of MTG.
