PTCG·LAB
A Toolkit for Pokémon TCG Pocket
PTCG·LAB is a free, browser-based toolkit for Pokémon TCG Pocket — analyse and compare decks, simulate pack openings with real pull rates, and track your luck. No account, no install, fully offline-capable.
⚠️ Heads up: decks are saved in your browser's local storage only. Clearing your browser cache or site data will permanently delete all your decks. Cloud sync via user accounts is planned for a future update — see the roadmap below.
Keep PTCG·LAB free & growing
Completely free, no data collection. If it's helped you build better decks or pull better packs, a small contribution goes directly toward new card data and development time.
Support on Ko-fi

What you can do
Card Explorer
Browse the full card database with filters for type, element, HP, rarity, retreat cost and abilities. Click any card for full details and related cards.
Deck Builder
Build 20-card decks, tag individual cards (e.g. FirstTurn) and configure custom Scoring Rules that tell the engine what a "good hand" looks like for that deck.
Fluidity Analysis
Run a single hand draw or bulk-simulate up to 10,000 games. See score distribution, top trigger cards, mulligan rate and turn-by-turn hand progression.
VS Battle
Head-to-head simulation between two decks. Single Run shows a turn-by-turn card-image replay. Bulk Battle gives win-rate, average score and a turn timeline across thousands of games.
Pack Simulator
Open packs using real pull rates. Simulate 1–100 packs, hunt a complete set, or run bulk simulations to find out how many packs you statistically need — with a Luck Meter to judge your pulls.
How the simulation engine works
The engine models the opening phase of a PTCG Pocket game — the turns that decide whether a deck "bricks" or flies out the gate:
- Mulligan — if neither player has a Basic Pokémon in the opening hand, hands are shuffled and redrawn (up to 20 times).
- T0 — Opening commit — all Basic Pokémon are placed to the bench; Tools and Stadiums attach automatically. Only Trainers and Supporters remain in hand.
- T1 / T2 (/ T3 / T4) — each turn: draw 1 card, play any eligible hand-accel or disruption cards (Poké Ball, Professor's Research, Red Card, Mars, Copycat), then commit new Basics / Tools / Stadiums.
- Score — after each turn, the remaining hand is scored against that deck's custom Scoring Rules. Higher score = better start.
⚠️ The engine does not simulate attacks, damage, or prize cards — it is a fluidity / consistency tool only.
Development Roadmap
✅
Phase 1 — Foundation
Card database · Explorer with filters · Deck Builder · Card tagging system
✅
Phase 2 — Fluidity Analysis
Simulation engine · Custom scoring rules · Single-run hand view · Bulk statistics · Score distribution charts
✅
Phase 3 — VS Battle
BattleEngine · Head-to-head deck comparison · Turn-by-turn single run with card images · Bulk battle win-rate statistics · Hand-accel & disruption effects · Turn selector (T2 / T4)
✅
Phase 4 — Pack Simulator
Real pull rates from official data · Open 1 / 10 / 100 packs · Complete Set mode · Bulk Sim (10–100 runs) with avg / median / distribution histogram · Luck Meter · Rarity target chips (choose which rarities count toward completion) · Full B3a Paradox Drive card database
🔜
Phase 5 — Deeper Battle Simulation
More registered effects (Giovanni, Sabrina, Cyrus…) · Energy attachment simulation · Attack simulation & damage calculation · Prize card tracking
🔜
Phase 6 — Meta & Community

Latest
May 2026
- 📦 Pack Simulator — open packs with real official pull rates for all 18 sets
- 🎲 Open Packs mode: simulate 1, 10 or 100 packs and see every card pulled with images
- 🏆 Complete Set mode: opens packs until every target card is collected, reports packs needed
- 📊 Bulk Sim mode: run 10–100 complete-set simulations, get avg / median / p25 / p75 / best / worst + distribution histogram
- 🍀 Luck Meter: animated needle showing how your pulls compare to statistical expectation
- 🎯 Rarity target chips: select exactly which rarities count toward "completion" — exclude Immersives, Shinies or Gold Crowns for more realistic goals; bonus pulls shown greyed-out in the card grid
