Blight Curse Commander Deck Upgrade Guide

Grave Titan is a strong card in a vacuum: a 6/6 deathtouch that makes two Zombies when it enters and whenever it attacks. But it costs {4}{B}{B}, does nothing with counters, and only about one Auntie Ool deck in eight plays it.

Nest of Scarabs costs {2}{B} and makes a 1/1 Insect for every -1/-1 counter you put on a creature. Every blight, every counter from Skinrender or Dread Tiller and every wither hit becomes bodies, and those bodies are fresh targets for your next blight.

Hoarder's Greed costs four mana, loses you 2 life and draws two, then clashes to repeat. It is fine, but this deck draws cards on its own.

Obelisk Spider is a 1/4 reach for {1}{B}{G} that puts a -1/-1 counter on any creature it damages in combat, and each time you put counters on a creature, each opponent loses 1 life and you gain 1. A sturdy blocker that grinds creatures down and triggers Auntie Ool when it connects.

Cathartic Reunion makes you discard two cards to draw three. That is a one-card gain at best, and Auntie Ool is already your engine.

Scuzzback Scrounger is a 3/2 for {1}{R}. At the beginning of your first main phase you may blight 1, and if you do you create a Treasure. Blighting your own creature puts a -1/-1 counter on it, so Auntie Ool draws you a card as well: a card and a Treasure every turn for a two-drop.

Harmonize is four mana to draw three cards, with nothing else on the card.

Dawnhand Dissident costs just {B}. {T}, blight 1: surveil 1. Each activation puts a counter on one of your creatures, which draws you a card with Auntie Ool out. {T}, blight 2 exiles a card from a graveyard, and you can later cast creature cards you own that it exiled by removing three counters from among your creatures.

Commander's Sphere is a three-mana rock in a deck that already has Sol Ring, Arcane Signet and three mana creatures.

Grim Affliction is an instant for {2}{B}: put a -1/-1 counter on a creature, then proliferate. One counter becomes several, and every creature that gains a counter is another Auntie Ool trigger. It also kills small creatures outright.

Ferrafor costs seven mana. It creates Saprolings equal to the number of counters among a player's creatures and can double the counters on a creature, but you need it to survive a turn to untap with it.

Ammit Eternal is a 5/5 for {2}{B} with afflict 3. Each time an opponent casts a spell it gets a -1/-1 counter, and because you control it, Auntie Ool draws you a card every time. When it connects with a player, all the counters come off and it resets.

Chimil is the most expensive card in the deck at about $8. It costs six, makes your spells uncounterable and discovers 5 at your end step, with no board presence and no counters.

Soul Immolation costs {3}{R}{R}. As an additional cost you blight X (X can't be greater than the greatest toughness among your creatures), then it deals X damage to each opponent and each creature they control. A one-sided sweep that also puts X counters on your creature, which draws you a card.

Liliana is a seven-mana planeswalker whose +2 puts a -1/-1 counter on a creature and whose -3 destroys a creature with one. It fits the theme, but seven mana is a lot for a deck whose engine works best on turn two.

Gristle Glutton is a 1/3 for {1}{R}: {T}, blight 1: discard a card, and if you do, draw a card. Each activation is a loot plus an Auntie Ool trigger, so you come out ahead on cards every time.

This is the first of two land-for-spell swaps. Terramorphic Expanse sacrifices itself to put a basic land onto the battlefield tapped, and the deck already has 39 lands, so it can drop to 37.

Shadow Urchin is a 3/4 for {2}{B/R} that blights 1 whenever it attacks. When a creature you control with counters on it dies, you exile that many cards from the top of your library and may play them until your next end step, which turns your blighted creatures into card advantage when they die.

The second land-for-spell swap. Evolving Wilds does the same thing as Terramorphic Expanse, a tapped basic, and the deck has plenty of fixing without it.

Blight Rot costs {2}{B} at instant speed and puts four -1/-1 counters on a creature. That kills nearly anything, and because the counters land on an opposing creature, its controller loses 1 life from Auntie Ool as well.

Archfiend of Ifnir is a 5/4 flier for {3}{B}{B} that puts a -1/-1 counter on each opposing creature whenever you cycle or discard. It is played in about one Auntie Ool deck in four.

Generous Patron is a 1/4 Elf Advisor for {2}{G}. When it enters you support 2, putting a +1/+1 counter on each of up to two other creatures, and whenever you put counters on a creature you do not control you draw a card. A cheap body that spreads counters and draws.

Cathartic Pyre is an instant that deals 3 damage or lets you loot. It is played in about one Auntie Ool deck in four.

Persistent Constrictor is a 5/3 Zombie Snake for {4}{B} with persist. At the beginning of each opponent's upkeep they lose 1 life and you put a -1/-1 counter on up to one creature they control. Auntie Ool drains for every counter on a creature you do not control, and persist brings it back.
