- The damage by Outside of the Hourglass is inflicted by the vampire using the card, which is a rare thing for card played before range is determined. Carrion Crows, Weather Control and the like all so-called environmental damage.
- After playing after Outside of the Hourglass, it doesn't matter if you played Strike: Combat Ends in the strike phase and don't inflict damage with that. Disarm does not require the vampire to inflict damage with a strike, only that the vampire inflicts damage himself (and not environmental damage).
The combination is strong, but far from unbeatable. The easiest defense against this, is just to maneuver to long range or to play damage prevention (requiring cards that are not limited to prevent damage from an opposing minion's strike).
