Guile Casting or playing
Hello.
If something instructs you to “play that card”, you play the card if it's a land or cast it if it's not a land. So in most cases, you're going to be casting the card that was just countered, and things that trigger when a spell is cast (like Guttersnipe or Dovescape) will trigger.
701.11b To play a card means to play that card as a land or to cast that card as a spell, whichever is appropriate.
