Because there is no dedicated format for BLW-LOT on TCGOne, players must use the Expanded Unbanned format to play each other. However, because this format has different First Turn Rules, participants must pass-pass at the beginning of each game so players can play supporter cards on their first turn going first. The player going first still cannot attack, and both players still cannot evolve any pokemon on their first turn. Failure to comply may result in a game loss.

When exporting your decklist from TCG ONE, cards from Celestial Storm must be changed from "CLS" to "CES" For example:

Swampert (CLS 35) should be changed to: Swampert (CES 35)
