Does Pyke, Returned see kills if he dies too, and does Ember Monk buff on countered hidden?
If Pyke, Returned and an opponent's unit die simultaneously, do I still get gold? If I counter a hidden spell, does Ember Monk still get the buff?

[Hidden] (Hide now for to react with later for
.)
[Backline] (I must be assigned combat damage last.)
Once each turn, when an enemy unit dies while I'm at a battlefield, play a Gold gear token exhausted. (It has "[Reaction][>] Kill this, : [Add]
.")

If Pyke, Returned and an opponent's unit die simultaneously, do I still get gold? If I counter a hidden spell, does Ember Monk still get the buff?
If Pyke, Harrower is exhausted, does he still ready himself as part of his play effect even if I choose not to pay his additional cost?
My opponent uses Pyke's legend to return a unit to hand. I respond by ambushing with Rengar to that battlefield. Does the bounce still happen before the showdown starts, or does the entire showdown resolve first before Pyke's legend goes off?
If one effect kills multiple units at once and some have Deathknell while others create normal death triggers like Pyke or Viktor effects, which triggers are placed first?
If Rek'Sai's effect lets me play a champion unit, can I ignore Accelerate's additional payment, or do I still pay Accelerate normally?
