Swift Strike Rulings
Combat damage is dealt simultaneously if the attacker and the thing it's attacking both have swift strike. — Sirlin
If swift strike damage kills a unit or hero in combat that does not have swift strike, the non-swift strike unit or hero dies before it gets a chance to deal combat damage. — Sirlin
Unstoppable Rulings
Having a detector (or a Tower add-on) doesn't help against the unstoppable keywords. Even then, unstoppable attackers can ignore patrollers. — Sirlin
