does bleeding wall get a counter for units that come into play corrupted w/ warpstone excavation?

No, because the BW states: "… When {chaos} units you control is corrupted, put a resource token on this card." and the unit, with WE in play, enters in play already corrupted.

Thanks Horatius. Can anybody else confirm this? This makes bleeding wall really good, but if it does not then it nerfs bleeding wall a little bit.

Contentious issue in our lil playgroup lol .. both good and bad .. one time i jealous eyes a few counters off of bleeding walls that shouldnt have been there haha

Q: If I control Fellblade (CC 100) and my opponent plays a unit into a zone containing a Warpstone Excavation (CS 116), is the unit considered to have been corrupted, allowing me to put a resource token on Fellblade?
A: No. A unit that enters play in a particular state is not considered to have changed states. So in this case there is nothing being corrupted to trigger Fellblade. However, if a unit already in play moves to the zone that contains Warpstone Excavation, then it is considered to have been corrupted and a resource token would be placed on Fellblade.
