Just a second

Just a second is a static ability introduced in Unstable on the card Slaying Mantis. It does not allow any players to move any card on the battlefield as long as the spell with just a second is on the stack.

Description
Just a second is a joke variant of Split Second that prevents players from moving cards on the battlefield.

Just a second is considered to have all of the effects of split second in addition to its own. This means that certain actions not covered by just a second's reminder text, like casting spells for no cost, are prevented by just a second.
