Je confirme pour VoSS. Voici l'explication que j'avais donnée aux HJ du GP Madrid :
Volrath's Shapeshifter does get a counter.
It comes from:
614.12. Some replacement effects modify how a permanent enters the battlefield. (See rules 614.1c–d.) Such effects may come from the permanent itself if they affect only that permanent (as opposed to a general subset of permanents that includes it). They may also come from other sources. To determine how and whether these replacement effects apply, check the characteristics of the permanent as it would exist on the battlefield, taking into account replacement effects that have already modified how it enters the battlefield, continuous effects generated by the resolution of spells or abilities that changed the permanent's characteristics on the stack (see rule 400.7a), and continuous effects from the permanent's own static abilities, but ignoring continuous effects from any other source that would affect it.
The last sentence tells us to look at the Shapeshifter as it would exist on the b/f, taking into account its own static abilities. Because of this, we see that it has the ability "comes onto the b/f with a counter", and it's an effect that affects only the permanent itself (second sentence above), so we apply it.
