counterTo counter a spell or ability is to cancel it: remove it from the stack without resolving it. A counter on an object or player is instead a marker that changes characteristics or interacts with rules or abilities; for example, a +1/+1 counter modifies a creature’s power and toughness.

A player can’t sacrifice something that isn’t a permanent, or something that’s a permanent they don’t control.

If multiple players scry at once, each of those players looks at the top cards of their library at the same time. Those players decide in APNAP order (see rule 101.4) where to put those cards, then those cards move at the same time.
An ability that triggers whenever a player scries triggers after the process described in rule 701.22a is complete, even if some or all of those actions were impossible. (CR 701.22) 2.
