Why do the war cries triggered by Rylak Metalhead have a temporary effect during combat and disappear when the turn is over ?
Does Young Murk-Eyes also have a temporary effect or is it permanent ?
(I couldn’t check because the servants died).

A war cry should be permanent !
Bug ?

Not a bug. Buffs during the combat phase are temporary unless an effect specificly stats that the effect is permanent.
Only buffs in the tavern are permanent.
Thanks for your answer. 
For me it didn’t say “permanent” because it goes without saying that a war cry is “always permanent” (for me it is logical).
It’s normal that a death rattle effect is “temporary”.
If the war cry is not permanent, it has almost no interest.
Big disappointment.
Any enchantment applied during the recruit phase is permanent unless explicitely indicated that it’s temporary.
Any enchantment applied during the battle phase (on the board) is temporary unless explicitely indicated that it’s permanent.
The interest of triggering battlecries during fights is mostly for those that do not benefit the board but either your hand or the tavern.
Battlecries that give you cards, buff your hand, buff the tavern affect the cost of tavern up, buddies, hero powers… Those are permanent buffs even if triggered during the fight
Yes, I know that in some cases it is useful.
This is a very good summary, but I still find it illogical that it is not a permanent effect 
(I do not have the courage to elaborate - lol)
