Derevi, Empyrial Tactician costs {G}{W}{U} and is a 2/3 Legendary Bird Wizard with flying. When it enters and whenever a creature you control deals combat damage to a player, you may tap or untap target permanent, and for {1}{G}{W}{U} you can put it onto the battlefield from the command zone. Every connecting creature taps a blocker or untaps a land.

The precon already has the flyers and the evasive pressure, including Sol Ring, Basalt Monolith and Arcane Denial. 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 Derevi decks, plus lift, which shows how much more often a card turns up in Derevi decks than in decks that could play it.

What to keep

These cards are doing the deck's heavy lifting. Do not cut them.

If you want to spend more

These are strong but sit outside a budget upgrade. Prices are the cheapest paper printing.

The verdict

Evasive Maneuvers already has the flyers and the evasive pressure that makes Derevi's tap and untap trigger work. The upgrade is cheap ramp, flyers and card draw, in place of situational creatures and slow mana rocks that Derevi decks leave out. These twelve swaps cost about $16 in total.

How the numbers work

Inclusion is the share of Derevi, Empyrial Tactician decks (11,874 of them when this was written, 2026-10-28) 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 Derevi decks, which flatters every card the precon contains. Lift stays low to moderate for these cards because most of them are played in many decks, so use inclusion and synergy to compare cards, not lift. 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.
