Another match- more questions

[FredSpaghett]

1. Can a model with a 50mm base stand on top of a Misiaki shadow marker (30mm base) to make her not able to unbury in base contact with that marker?

 

2.  Can Mactavish not put his swamp screen marker under his own base?

 

3. Do you get pass tokens from getting fewer models than your opponent when your models dies? 
 

 

Thanks!!!!

1. Yes. They're not impassible, and if a 40mm+ model is standing on top of it, she is unable to make base contact to unbury. 
2. He can. "Created Markers cannot be put into base contact with any models except for the model creating them. Impassible Markers cannot be Created in such a way that their base overlaps the base of the model creating them." Since McTavish's swampscreen is not Impassible, the clear negative case of the second sentence is that his base can overlap the marker. 
3. No. Assuming you mean after the pass token generation step at the beginning of each turn, you do not get pass tokens for dead models to make up for lost activations. The only time the rules of the game (as opposed to models that just expressly generate tokens) generate pass tokens is during summoning, and after initiative is flipped. This means killing unactivated models gives the aggressor an activation advantage over their opponent, and is an important part of a lot of strategies.
