You don't think the best Wolverine team has Mystic Ray backing him? Angelic's play makes PR Rog look cautious.
If you could have 3 assists on a team then the two I mentioned plus this would be all Wolverine needs.
Angelic uses Mystic Ray for 3 main things. Pick up after throw (both Jam Session/Plasma Beam do this), to get in with full screen Berserker Slash (Plasma Beam does this) and to pressure opponents at SJ height (which Jam Session also does just in different ways). You could also argue that Mystic Ray has the same defensive property of Plasma Beam but to that I say that Plasma Beam does it better because it's faster. Mystic Ray does not give Wolverine instant overhead/fuzzy mix ups which he wants for sure and Jam Session/Tatsu give him that.
For an optimum Wolverine team featuring Mystic Ray you need Tatsu/Jam Session assist for sure. It actually some what works out because Skuma can use Tatsu. I would still say that Doom/Dante is a bit more stable than this as you have access to superior TACs and THCs. I also feel Dante is a better anchor than all of those other support characters.
In any case the top 5 assists for Wolverine are (no order);
Tatsu
Jam Session
Plasma Beam
Mystic Ray
Drones
Honorable mention: Rocks
Drones I added an extra because the mix up potential for Wolverine if he gets you in Drones is higher than any other other assist. With those assists you generally only have to make one maybe two guesses with Drones you will have to take a minimum of two even three mix ups at a time. It allows Wolverine to go for Berserker Slash while they are locked down because of the Drones gap.
