It activates the skills of the other cards in your team, provided those skills are not Autoskill or another skill unleash.

The only unleash-able autoskills are the null ones:
 * Category:Skill Nullify
 * Category:Skill Nullify (Non-Attack)
 * Category:Skill Nullify (Attack)

And Santiclaus is the only card that has unleash skill but can be activated by other unleashers because she is mainly considered a random skilled card, rather than an unleasher.
