Rule 359.3.e.10

It is possible for none of a spell's instructions to be executed as it resolves, due to all of them requiring targets to act on and all of those targets becoming Invalid or Unavailable. In this case, the spell has no effect but is still considered played. Example: A player plays a spell that reads "Deal 2 to a unit at a battlefield" with no other instructions, and chooses an enemy unit at a battlefield. They also control a unit with the ability "When you play a spell, give me +1 [M] this turn." Before the spell resolves, the chosen unit is moved to its base. The spell resolves and its only instruction cannot be executed, but the unit's ability still triggers as the spell resolves and gives it +1 [M].
