Testing Magic: The Gathering decks before buying expensive cards is smart financial planning. This guide covers the best methods for testing decks, from proxies to digital tools, so you can make informed purchasing decisions.

Why Test Before Buying?

Testing decks helps you:

Method 1: Proxies (Physical Testing)

Creating Proxies

The most common method for physical testing:

  • Physical setup needed

Proxy Best Practices

Method 3: Goldfishing (Solo Testing)

What is Goldfishing?

Playing your deck against an imaginary opponent who does nothing.

How to goldfish:

  1. Shuffle deck
  2. Draw opening hand
  3. Play as if opponent does nothing
  4. Track results - How fast can you win?
  5. Repeat multiple times

What Goldfishing Tests

  • Mana curve - Do you have enough lands?
  • Consistency - Does deck work reliably?
  • Speed - How fast can you win?
  • Synergies - Do cards work together?

Limitations

  • No interaction - Opponent doesn't respond
  • Unrealistic - Real games have interaction
  • Limited value - Doesn't test against strategies
  • Best for - Initial testing only

Method 4: Playtesting with Friends

Organizing Playtests

  1. Ask friends to help test
  2. Use proxies for expensive cards
  3. Play multiple games - Best of 3 or 5
  4. Take notes - What works, what doesn't
  5. Iterate - Make changes and retest

What to Test

  • Against different decks - Various strategies
  • Going first/second - Both scenarios
  • Mulligan decisions - What hands to keep
  • Sideboard plans - Post-board games

Getting Feedback

Ask opponents:

  • What felt strong?
  • What seemed weak?
  • What was surprising?
  • How did it feel to play against?

Method 5: Theorycrafting and Analysis

Deck Analysis Tools

  • EDHREC - See popular cards and strategies
  • MTG Goldfish - Meta analysis and decklists
  • Scryfall - Card search and analysis
  • Deck building sites - Test mana curves

What to Analyze

  • Mana curve - Distribution of costs
  • Card synergies - How cards work together
  • Meta matchups - How it fares against popular decks
  • Win conditions - How you plan to win

Limitations

  • No actual play - Theoretical only
  • May miss interactions - Real play reveals issues
  • Meta assumptions - May not match your meta
  • Best combined with other methods

Comprehensive Testing Strategy

Phase 1: Initial Testing

  1. Goldfish the deck 10-20 times
  2. Check mana curve - Is it reasonable?
  3. Verify synergies - Do cards work together?
  4. Identify issues - What needs fixing?

Phase 2: Proxy Testing

  1. Create proxies for expensive cards
  2. Play with playgroup - Get real game experience
  3. Test against variety - Different deck types
  4. Track results - Win rate, what works

Phase 3: Refinement

  1. Make adjustments based on testing
  2. Retest changes - Verify improvements
  3. Optimize list - Fine-tune card choices
  4. Finalize build - Ready to buy

Phase 4: Purchase Decision

  1. Evaluate results - Did deck perform well?
  2. Consider cost - Is it worth the investment?
  3. Check enjoyment - Did you have fun?
  4. Make decision - Buy or don't buy
