Guard vs Clones I believe the trigger is instant, so when knocking out a guard on the same tile as a clone, it instantly consumes the guard and from that moment onward they take the opposing factions fear/threat-level into consideration when selecting target during their activation.
For Scenario 2
If any number of clones share a tile with a stunned guard, removed the guard
If guard out number clones on a tile, remove the clone.
When does we compare this Guard vs clone trigger requirement ? When is it trigger?
Player A is on the same tile with Guard 1 and Clone 1 and on his turn he decide to attack the guard result in stunting the Guard 1. Do the above Guard vs Clone come into play and we removed the Guard 1 ?
On enemy actviation , Guard 1 had no valid target , so Guard 1 move to a tile contain Guard 2 and Clone 1, do we removed the Clone 1 straight away , then after that Guard 2 move ?
A guard with no valid target would not move onto the tile with the other guard and the clone, unless it was on it's way to a valid target (the clones are not considered valid targets until after guard vs. aliens has been put into play).
But yes, if guard 1 steps onto the tile with guard 2 and clone 1, they instantly kill clone 1 and when guard 2 activates, it takes all other clones on the board into consideration when selecting it's primary target.
That's how I think it is at least
