The Necromancer is a reliable choice for one of the Undead slots. As one of the finest units in the Undead faction, it can take advantage of Sylvanas’s speed aura. In addition, a front-row unit is needed. The 4-cost Stonehoof Tauren is a strong recommendation. It can topple the opponent’s rear-guard, but it does not possess AoE capabilities, necessitating the use of Sylvanas’s “Black Arrow” talent. Another fitting undead unit suggestion is the Skeleton, endowed with the “Exhume” talent. As a cost-effective tower support unit for the Unbound, it aligns well with Sylvanas’s build.

The composition for the three slots at the bottom remains uncertain (details will be available after the Undead week). Temporarily, units like Bat Rider, a high-value ground AoE unit, are recommended because of Sylvanas’s strong anti-air capabilities. Quilboar is another good option as it can provide distance support and function as an elemental tank. The final slot could be filled by the S.A.F.E. Pilot, who can lend remote support and has potent AoE skills.
