Reduces the user's sync move countdown by one the first time it enters a battle each battle. When used in a co-op battle, reduces the user's sync move countdown by one the first time your team enters a battle each battle instead. The more allied sync pairs with the Sinnoh theme you have on your team, the greater the reduction is. (Each additional sync pair increases the reduction by one, and the maximum reduction is three.) The effects do not stack if you have more than one sync pair on your team with passive skills of the same name.
When a user with this skill is on the team, the sync move countdown is reduced by the number of sync pairs with the Sinnohtheme skill at the start of the battle. The minimum reduction is one, and the maximum is three. This skill does not stack if multiple sync pairs with the skill are on the same team.
