After Patch 9.7 consequences of Death can only work if their position and controller are valid before Death Creation Step.

' can only work if they're valid when the Sequence starts.

After Patch 9.7 triggers in a Sequence that read 'After.

However, they can Queue on any later Phases and Events created.

Minions and Secrets summoned while resolving an Event cannot respond to Events that are in the middle of resolution, because their associated Queues are now immutable.

Minions, Heroes, Weapons, Secrets, attached Enchantments and added Deathrattles are all Entities, and all exist in the same order of play list together.

Order of play means the order the Entities each Event/trigger is associated with entered play, from oldest to newest.

No new entries can be added to the Queue after this point. Rule 2c: A Queue becomes immutable once Hearthstone starts to resolve the first entry in it. Here is a very complicated series of triggers as a result of playing Feign Death in The Masked Ball. Here is an example of deeply nested triggers during Death resolution.

Here are three more examples of deeply nested triggers during the playing of a minion.

Here is an example with Knife Juggler and Grim Patron.

Hearthstone kills both minions, removing them from the board. There are no further consequences, so the phase is resolved. The Dragon Egg immediately spawns a Black Whelp, causing the Knife Juggler to trigger and throw a knife (even though both are mortally wounded, because death is not checked during resolution).

You Flamestrike a Dragon Egg and Knife Juggler.

If a player concedes in a Swedish style bracket, the result is.

Instead it works the skipped times as a compensation after all other consequences of it are resolved.

It seems that a trigger cannot be nested inside itself.

When a trigger/Event is resolved, Hearthstone picks up where it left off.

The moment a new trigger/Event is raised, Hearthstone begins to resolve it and immediately begins exploring its consequences, before resolving those remaining for the current trigger/Event.

(If multiple events could be partially resolved, that would be breadth-first).

When multiple events are awaiting resolution, the need to resolve an event before starting the next is a depth-first resolution.

The numbers on each circle are the order Hearthstone would resolve them in. The process of resolving an event is similar to a depth-first search - Imagine every circle being an event and every arrow representing a trigger starting a new event. Rule 1c: Death is not checked during the standard resolution of Events. Advanced mechanics 101 (READ THIS FIRST) Sequences, Phases, Queues, Resolution
