Pauper on MTGO

I've recently been introduced to this super fun format by friends (and a recent article by LSV). If you don't know what Pauper is, it's a format online where your sixty card constructed deck consists of nothing but commons. The best part about the format is that you can build a deck that's cheap, but still competitive (My friend has an affinity deck that apparently only cost 8-10 tickets).

As soon as I decided I wanted to jump into the format, I looked at a site that holds Pauper tournaments and had the top decklists (PDCMagic). I chose to build a storm combo deck that just did well at a recent tournament.

I decided on this deck because it resembles Goblin Charbelcher from Legacy, a deck that I really enjoy playing. The deck is super fun, and consistently spits out about 30 goblins by turn 4-5, or Grapeshot's their face for lethal. I've also been working on a mono green infect deck that uses pump spells like Invigorate and Groundswell to kill the opponent as quickly as turn 3.

I've heard that the format is very narrow and that people only play decks like storm combo, mono blue control or mono black, but I haven't seen much of those decks. I've seen a ton of different archetypes... G/W tokens, infect, U/R control, Kiln Fiend decks, all kinds of stuff. I don't think I've played against the same deck twice yet besides Affinity which is kind of common. Hopefully you'll try out this format and like it as much as I am so far. Any format where a card like Sigil Blessing is good has to be awesome.
