Card-Specific Rulings
If this doesn't have a crumbling rune on it and it would die, it doesn't actually die so nothing that triggers on "dies" will happen. For example, it won't draw a card if it "would die" in the technician slot, only when it really does die after it has a crumbling rune on it. — 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
