Dina, Essence Brewer costs {1}{B}{G}. Whenever you sacrifice a creature she draws you a card, once each turn, and for {2}, a tap and another sacrificed creature she gains you X life and puts X +1/+1 counters on a creature, where X is the sacrificed creature's power. Every Pest you sacrifice is a card.

The precon already has the Pest makers and the engines, including Beledros Witherbloom, Pest Rescuer and Morbid Opportunist. Each swap below pairs a cut with an add, and every card is scored with the same numbers the Oracle uses to build decks: synergy and inclusion from the Dina decks, plus lift, which shows how much more often a card turns up in Dina decks than in decks that could play it. The precon is close to what players build, so this guide has five swaps.

What is holding the deck back

Missing sacrifice payoffs

Cauldron of Essence, Moseo, Jenova and Meren are the top-scoring cards the precon leaves out, and each turns creatures dying or being sacrificed into drain, recursion or counters.

A few cards that do not fit

Gyome, Master Chef is a Food maker that is not a card Dina decks usually play. Casualties of War costs six, and the deck already has Toxic Deluge and Final Act for sweeping the board.

A low curve that can afford better cheap cards

Only three nonland cards cost six or more, so the slots at two to four mana are where the upgrades go.

Casualties of War costs {2}{B}{B}{G}{G} to destroy an artifact, a creature, an enchantment, a land and a planeswalker. It is a six-mana sorcery in a deck that already has other sweepers.

Jenova, Ancient Calamity is a 1/5 for {2}{B}{G}.

How the numbers work

Inclusion is the share of Dina, Essence Brewer decks (12,141 of them when this was written, 2026-10-27) that play the card. Synergy is how much more often they play it than other decks in the same colours. Oracle score is synergy × 0.6 plus inclusion × 0.4, the same blend The Oracle uses to rank cards for a deck. Lift compares how often the card appears in these decks with how often it could, capped at 8× here; it is shown for context and does not change the score.

Two cautions. Players who run the precon unmodified count as Dina decks, which flatters every card the precon contains. Lift is moderate for most of these cards because they are played in many Golgari decks, so use lift to compare cards, not to judge one in isolation. A card the commander's decks do not usually play counts as 0 in the average score. Prices are the cheapest non-foil paper printing on TCGplayer (via Scryfall), in USD, and move daily.
