Hour of Education

Split Second (As long as this spell is on the stack, players can't cast spells or activate abilities that
aren't mana abilities.)
Until your next turn, all permanents are tapped,
and lose all abilities. Until your next turn, players
can't cast spells and skip their attack phase. They
do the same with their untap step, upkeep, draw
step, main phases, and end step.
Your opponents can't pass the turn.
