Mtg Synergy Calculator

Building the perfect Magic: The Gathering (MTG) deck is both an art and a science. Whether you’re a casual player or a competitive strategist, one of the biggest challenges is understanding how often you’ll actually draw the cards you need for your combos or synergies. That’s where the MTG Synergy Calculator comes in.

This powerful, easy-to-use tool helps you determine the probability of drawing specific combinations of cards in your deck. By using hypergeometric probability, it gives you accurate odds of seeing combo pieces, synergy cards, or support spells in your hand.

With this calculator, you can confidently adjust deck size, card counts, and synergy types to maximize your chances of victory.

How to Use the MTG Synergy Calculator (Step-by-Step)

Using the MTG Synergy Calculator is simple. Here’s a quick guide:

1. Enter Your Deck Size
   • Input the total number of cards in your deck (e.g., 60 for a Standard deck or 100 for a Commander deck).
2. Enter the Number of Target Cards (Combo A)
   • Specify how many copies of your first key card are in the deck.
3. Enter the Number of Synergy/Support Cards (Combo B)
   • Input the number of supporting combo pieces or synergy cards.
4. Enter the Cards Drawn
   • Add up your opening hand and any draws you expect (e.g., 7 + 3 turns = 10).
5. Select the Synergy Type
   • Choose from:
     • At least one of each – For combos that require both pieces.
     • Both together – For decks that need both cards in hand simultaneously.
     • Either piece – For flexible decks where either card advances your strategy.
6. Click “Calculate”
   • The tool will run the probability formula and show your synergy odds.
7. View the Results
   • The results panel highlights your probability, detailed breakdown, and synergy type.
8. Copy or Share Results
   • You can copy results to your clipboard or share them with friends for collaboration.

Practical Example

Imagine you’re building a Commander deck with a 100-card deck size. You want to know the chances of drawing Sol Ring (1 copy) and a support artifact (5 copies) within your first 10 cards drawn.

• Deck Size: 100
• Target Cards (A): 1
• Synergy/Support Cards (B): 5
• Cards Drawn: 10
• Synergy Type: At least one of each

After running the calculation, the MTG Synergy Calculator might show you something like:

• Probability of Drawing Synergy: ~43.5%
• Interpretation: Nearly half the time, you’ll see the combo by your 10th card, making it a fairly consistent synergy.

This insight helps you decide whether to add more support cards or tutors to improve consistency.
