4 AI-Powered Tools to Elevate Your Game

State-of-the-art AI features that no other MTG tool offers

🏗️

AI Deck Builder

5 tokens

Describe the deck you want in plain text — "red aggro Modern" or "Atraxa Commander with +1/+1 counters" — and AI builds a complete 60 or 100-card deck with sideboard, strategy notes, key cards, and upgrade path. Can also build using only cards from your collection.

AI Synergy Finder

3 tokens

Enter 1–5 seed cards and AI finds the most synergistic cards to build around them. Results are grouped by role: Enabler, Payoff, Removal, Ramp, Support. Perfect for brewing new archetypes from scratch.

🪞

AI Card Twins

3 tokens

Find functional equivalents for any card. Discover budget replacements, upgrades, or cards that do the same thing with a different name. Each twin is rated: Functional Copy, Superior, Inferior, or Lateral.

AI Deck Boost

5 tokens

Chat with AI to improve any saved deck. Ask for specific changes — "make it faster", "add more removal", "cut the weakest cards" — and AI applies targeted modifications while explaining every choice. Full session memory.

🤖

AI Deck Analyzer

3 tokens

Select any saved deck and choose an optimization goal (Aggro, Control, Combo, Tribal, Token…). AI analyzes mana curve, identifies synergies and combos, and suggests specific cards to add or remove.
