Starseer Mentor puts a constellation-style draw engine on board — each enchantment you cast replaces itself, which compounds fast in any deck built around enchantments. The cost is a three-mana 2/3 with no immediate impact, so it lives or dies by how quickly you follow it with spells. In Zoraline, Cosmos Caller it's an auto-include; everywhere else, it needs density to justify the slot.

Commanders with the highest synergy
Zoraline, Cosmos Caller
Zoraline, Cosmos Caller's entire game plan is casting enchantments repeatedly, which means Starseer Mentor turns every iteration of that loop into a free card — the synergy score of 0.78 and 80% inclusion rate reflect that this isn't a nice-to-have, it's structural to the deck.

Starseer Mentor is a Commander card through and through — the payoff scales with the number of enchantments you cast over a full game, which is exactly the resource environment a 100-card singleton format provides. In 60-card formats like Modern and Pioneer, enchantment-heavy strategies exist but the card is too slow and too conditional to compete with more efficient draw engines. Standard is its only realistic non-Commander home, and only in a dedicated enchantment shell where the density is high enough to fire the trigger multiple times per game. Anywhere outside of Commander, treat it as a bulk rare with narrow application.

Price Context
Current price
$0.09 bulk tier
At $0.09, Starseer Mentor is deep bulk — pickup cost is negligible for any Zoraline, Cosmos Caller or enchantress build that wants it. Bulk rares tied to a single popular commander can tick up with demand, but at current prices there's no reason to hesitate on copies.
