Celestial Lexi's MTGA Deck Randomizer

Let Celestial Lexi draw a moonlit deck for you from the Twilight Academy archives. Choose your colors, set the rules, test your opening hand, then carry the finished spellbook into MTGA.

Deck Settings

0 cards loaded

Quick single-set picker. Use “Allowed sets” below when you want one set, several sets, or all sets clearly.

Allowed sets Choose all, one, or several sets

This is the real set filter for deckbuilding. Choose one set if you only want cards from that set, or select multiple sets for a mixed card pool. Lexi keeps the Arena-only setting on unless you turn it off.

Selected sets: All embedded sets

Leave this on so I only choose cards you can use in MTG Arena.

Choose your colors directly, or let a shortcut mark the colors for Celestial Lexi.

Named color shortcuts Guilds, shards, wedges, four-color, five-color

Two-color guilds

Three-color shards and wedges

Four-color and five-color

Strategy shells Tap to hide/show recipe choices

Recipe target editor Optional overrides

Leave blank to use the default recipe. Add numbers only when you want to force a target, like 10 ramp pieces or 8 removal cards.

Locked cards / Must include Build around specific cards

Add cards here when you want the deck to start with fixed copies, then Celestial Lexi fills the remaining slots.

Card memory / backup Manual corrections that survive reloads

Next Build Steps

  • Leave this on so I only choose cards you can use in MTG Arena.
  • Primary style affects the card weights: Aggro, Midrange, Control, Ramp, Artifacts, Equipment, Tokens, Counters, Spells, Sacrifice, Graveyard, Lifegain, Flying, Heroes, Villains, Legends, Vehicles, Teamwork, Power-Up, Synergy, or Jank.
  • The summary panel shows mana curve, type counts, color counts, and why the deck leaned that way.
  • The Card Browser at the bottom lets you inspect cards manually, including tags, roles, synergy, rules text, and current-deck copies.
  • Seeded randomness is still intentionally paused for a later version.
