Discarded trigger can fail when depending on static

When you discard a non-Spirit creature with _Maskwood Nexus_ in play _Shipwreck Sifters_ does not trigger.

Easy fix would be using the new card from ``GameAction.changeZone`` to run the trigger instead of the old hand version.

Only question is if it should also trigger if you use _Ashes of the Fallen_ instead because it only affects Graveyard.

But I think it should probably too?
> 603.10. Normally, objects that exist immediately after an event are checked to see if the event matched
any trigger conditions, and continuous effects that exist at that time are used to determine what the
trigger conditions are and what the objects involved in the event look like.

No LKI exception does apply here

As bonus we could then finally use ``Defined$ TriggeredCardLKICopy`` on cards like _Bag of Holding_.
