Practice Arena
The Practice Arena is a rules-accurate practice mode for the One Piece Card Game. Pilot your own deck or a current meta list, play full games against an AI opponent and read the Battle Report to see where the game turned.

In short: Mugipocket’s Practice Arena is a One Piece TCG practice simulator for iPhone and Android. It runs full games against an AI opponent, with DON!!, blockers, counters, triggers and Life handled by a rules engine, and ends every match with a Battle Report. It is built for learning and for preparing for real tables; it is not an official product and match results are not official.
Rules engine
Attacks, blockers, counters, triggers, DON!! attachment and Life are resolved by a rules engine, and the AI opponent plays its own deck to win. You practice the decisions that matter at a real table.
Your deck vs the meta
Bring a deck from the builder or pick a current meta list, then play the matchups you expect at your next event and learn how each Leader wants to win.
Build a deck first
Battle Report
After each game the Battle Report walks through the turns that decided it, so a loss tells you what to change instead of just ending.
