Je viens de voir ça sur la base oracle :
http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=406195
If Centaur Vinecrasher and a land card are put into your graveyard at the same time, Centaur Vinecrasher’s last ability will trigger. It doesn’t matter what zone Centaur Vinecrasher was previously in.
Il semblerait que ça marche aussi dans le cas d'un
Jokulhaups
J'ai fini par trouver le point de règle associer (enfin je crois) :
603.6d Normally, objects that exist immediately after an event are checked to see if the event
matched any trigger conditions. 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. However,
some triggered abilities must be treated specially. Leaves-the-battlefield abilities, abilities that
trigger when a card leaves a graveyard, abilities that trigger when a permanent phases out,
abilities that trigger when an object that all players can see is put into a hand or library, abilities
that trigger specifically when an object becomes unattached, abilities that trigger when a player
loses control of an object, and abilities that trigger when a player planeswalks away from a
plane will trigger based on their existence, and the appearance of objects, prior to the event
rather than afterward. The game has to “look back in time” to determine if these abilities trigger.
On est dans un trigger qui check une carte qui arrive dans le cimetière, on suivrait donc la règle normale qui consiste à vérifier la condition après la résolution de f'effet. Je pense que tu as confondu avec le cas des capa "quand machin quitte le champ de bataille". On a bien des permanent qui quitte le champs de bataille avec Jokulhaups, mais le trigger concerné n'as rien a voir.
J'ai juste ?
En tous cas pas de doute en cas de dredge c'est faisable.
