Secrets of Strixhaven Quandrix Unlimited Commander Precon Upgrade Guide

Magic: The Gathering's Secrets of Strixhaven Quandrix Unlimited Commander precon focuses on casting X-spells, with its commander reducing costs as the game progresses. It can scale into powerful plays, but it benefits from more efficient ramp and stronger payoffs.

In this guide, we'll cover the best upgrades to improve its consistency, support its X-spell strategy, and increase its overall power.

Pensive Professor

Pensive Professor from the Secrets of Strixhaven main set works really well with Quandrix Unlimited precon. It grows bigger as you spend more mana to cast your spells through the new Increment mechanic. Additionally, it lets you draw a card when +1/+1 counters are put on it. Because the Quandrix Unlimited precon has plenty of +1/+1 counter support, this creature can draw you many cards.

Terrasymbiosis

Terrasymbiosis is a great card draw engine in decks that care about putting +1/+1 counters on creatures. It lets you draw cards whenever one or more +1/+1 counters are put on a creature you control. The number of cards you draw scales with the number of +1/+1 counters placed on a creature. If used in conjunction with Zimone's triggers, this can draw you two extra cards per turn.

Broodguard Elite

Broodguard Elite is an creature that enters with +1/+1 counters on it based on how much mana is spent casting it. Additionally, it lets you transfer its +1/+1 counters to another creature you control when it leaves the battlefield. This helps accelerate Zimone if you transfer the counters onto her. Moreover, this creature can also be warped to guarantee you can transfer its counters without it dying in combat or getting removed.

Branching Evolution

Brancing Evolution is a green enchantment that's a standout in decks focused around +1/+1 counters. This enchantment doubles the amount of +1/+1 counters that creatures you control would receive. When combined with Zimone, it can drastically accelerate her if this is left unchecked.

Wan Shi Tong, Librarian

Wan Shi Tong, Librarian is one of the best X-creatures you can add to the Quandrix Unlimited precon. This creature enters with a number of +1/+1 counters on it based on the value of X. Additionally, it also lets you draw cards equal to half that value. Moreover, Wan Shi Tong, Librarian also punishes opponents when they search their libraries. It grows bigger when they do so and also rewards you with additional card draw.

Quandrix Unlimited has a strong scaling engine, and upgrades help it reach that power faster and more reliably. Once tuned, it can turn its X-spells into game-ending plays.

By improving ramp and payoff density, the deck can consistently convert its resource advantage into wins.
