Deck Building Guide

Lorcana Deck Building Rules Explained

Every legal Disney Lorcana deck follows three core rules. Learn them once, and the rest of deck building is strategy — especially if your tools check legality for you.

The three core rules

• At least 60 cards. There's no maximum, but competitive players stay at exactly 60 — every extra card dilutes your best draws.
• At most 4 copies of any card with the same full name. The full name is what counts: you can run 4× Elsa – Snow Queen and 4× Elsa – Spirit of Winter in the same deck, because they're different cards.
• Up to 2 ink colors. Choose two of the six inks — Amber, Amethyst, Emerald, Ruby, Sapphire, Steel — and every card in the deck must belong to one of them.

Formats: where your deck is legal

Core Constructed

The standard competitive format. Alongside the core rules, only cards from the current rotation are legal — as of July 24, 2026, that means Sets 9–13 (Fabled through Attack of the Vine!). Rotation happens once a year, so a Core-legal deck needs an occasional checkup.

Infinity Constructed

The eternal format: every set ever printed is legal (minus the ban list). If you loved a deck that rotated out of Core, it lives on in Infinity.

Casual & Triple Deck

Kitchen-table play doesn't need rotation rules, and Triple Deck is a lighter event format played with smaller decks. Both are great ways to use more of your collection.

Beyond legal: what makes a deck good

• Watch your ink curve. A deck full of expensive cards does nothing in the early turns. Aim for a curve that lets you play something meaningful every turn.
• Keep enough inkable cards. Uninkable cards can't be placed into your inkwell — too many, and you'll stall on resources.
• Build around a plan. Quest aggressively, control the board, or ramp into bombs — pick one and make every card serve it.
