Slimed - Trickbind - [Borderless] Secret Lair Drop (SLD)

Split second (As long as this spell is on the stack, players can't cast spells or activate abilities that aren't mana abilities.) Counter target activated or triggered ability. If a permanent's ability is countered this way, activated abilities of that permanent can't be activated this turn. (Mana abilities can't be targeted.)
