Game Stories: Keeping Tempo

This week, I'm talking about two games that I've enjoyed immensely: Star Realms and Hearthstone. They're both card games (although Hearthstone is primarily digital) There's a lot of little things that come together about these games, but there's one particular storytelling area that they both touch on: the concept of tempo. "Tempo" refers to the fact that, in a turn-based game, one player will be the aggressor, while the other player attempts to respond to them. If that player can turn the tables with their response, they seize tempo. So how does that work out in these games?
