What Does Infinite Hourglass Do?
Infinite Hourglass is a Relic card, meaning that it's played on your main character rather than on a specific unit. From there it buffs all your units.
Whilst this cards is in play, all of your units on the battlefield have the endurance skill. This means that they never become exhausted - they can attack on your turn then defend on your opponent's. They are also immune to stun effects, for example those caused by Civic Peacekeeper or Permafrost.
Infinite Hourglass also protects against Execute... most of the time. If a unit blocks then it becomes exhausted until the end of the attacker's turn - even if it has the endurance ability. So if you can get your opponent to block an attack of your unit you can then use Execute on it that turn.
