Combo Probability Simulator
Estimate how often you open combo pairs in your starting hand across a range of deck sizes. Configure pairs, optionally import a .ydk deck, then run a simulation in your browser.
Deck Settings
Configure 1-card starters, deck-size sweep, hand sizes, and iteration count.

Combo Pairs
Each row represents a 2-card combo. The simulator reports the odds of opening at least one copy of both cards in your starting hand.
| Card A | Copies | Card B | Copies | |
|---|---|---|---|---|
Import .ydk
Upload a YDKE-compatible .ydk file to populate combo pair suggestions from your main deck. Card names are resolved using the YGO Combo Builder card database.
Run Simulation
Heavy runs (200,000+ iterations) execute in a Web Worker to keep the UI responsive.
Add at least one complete combo pair or set a non-zero starter count.
Configure your combo pairs and run a simulation to see opening probabilities by deck size.
