What it does
This enchantment enters with X study counters on it.
When this enchantment enters and whenever you cast your first spell with X in its mana cost each turn, create a 0/0 green and blue Fractal creature token. Put a number of +1/+1 counters on it equal to the number of study counters on this enchantment.
Rulings
2 official rulings, in the order Wizards published them.
- 2026-03-20
If you cast your first spell with X in its mana cost during a turn before Lattice Library is on the battlefield (including Lattice Library itself), casting another spell with X in its mana cost later in the turn won't cause its last ability to trigger.
- 2026-03-20
Lattice Library's last ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered or otherwise leaves the stack.
Rulings are Wizards of the Coast's own, mirrored from Scryfall and refreshed nightly.

Aggregated from Commander games tracked in TurnZero HQ. Every figure counts decks and games only. No individual deck list, player or playgroup is identified. Win rates are withheld below 5 completed games, where the sample is too small to mean anything.
