A week ago decided to get back into Magic the Gathering and play the Modern format. I made an MTGO account and my first deck was the preconstructed mono-green infect deck (which I have since turned into simic infect). Next, I decided I wanted something more stax related. I had heard of 8 racks and saw that the core pieces weren't too expensive, so I decided to build a budget version of that.

Hoo boy does my budget 8 racks suck but I had a blast playing it. I promise not to play it that often, this was a guilty pleasure (I felt so bad torturing my opponents). I've decided to try to upgrade it based on my (probably retarded) theories of what might be good.

4 thoughtseizes

4 Inquisition of Kozilek

4 Raven's crimes

2 Blackmails

3 Wrench Mind

4 Racks

4 Bandit Talents

2 Davriel Rogue shadowmage planeswalkers

4 smallpox

3 toxic deluges

3 dismembers

3 Mishra's factories

3 mutavaults

15 swaps

2 Urborg, Tomb of Yawgmoth

I had 4x shrieking affliction but I though the card wasn't good. I frequently was not able to get my opponent's card count down to 1 or less, and shrieking affliction did nothing in the early game. It was often a dead card. To this end, I decided to go to 10 rack cards, with the Rack, Davriel, and Bandit. I might do 2 Bandit Talents, 2 Shrieking afflictions, but I'm not sure.

6 of the Rack cards have built in discard which should give me more consistent value. With 6 manlands as opposed to 4 manlands, this also means I have 16 sources of consistent damage as opposed to the traditional 12 sources of damage (tradition being 4 racks, 4 shreiking afflictions, 4 mutavaults).

I made what was probably a retard decision to not include Liliana. This is partially because it requires 2 black mana and I have 6 colorless. But also, I don't like how she requires me to discard for her +1. I feel like that is bad value. More of my baseline cards have discard effects and I have toxic deluge, so I think that will make up for Liliana's exclusion.

I don't know what decks to sideboard for or which cards to sideboard out for what. Anything related to the sideboard is a mystery to me. I do think Burn and Aggro might be a problem given toxic deluge and dismember in the deck, maybe that's what I should sideboard for?

Any thoughts on my decklist?
