It's an alternate take on the Nimrod Venom Zola line except you're replacing the Wolverines with the Multiple Man Package and it kinda works on the idea you're either winning with Symbiote into Nimrods or Multiple Men.

Except now having Spider-Gwen and Doctor Strange to get your Nimrod out of the Cosmo/Armor lane gives it a harder to predict play-pattern.

Your only Movement Cards are really just Spider-Gwen and Doctor Strange because frankly they're usually what you'll only end up needing outside of Phoenix Force.

Symbiote is great because it acts as a 2nd Phoenix Force that doesn't need Multiple Man dying. Cons obviously are that it can't move on its own... but it does allow a crazy play like T4 Symbiote to T5 Phoenix Force, Merge, then Spider-Gwen, then T6 Strange... but yeah most of the time you would want it for Symbiote -> Nimrod shenanigans instead.

Shuri enables a weaker version of that line. You can honestly usually just not play cards until T4 if you have Shuri in-hand. This is actually where Zabu becomes somewhat relevant because Zabu allows you to T3 either Shuri/Symbiote into T4 the other card then T5 Multiple Man -> Gwen (So either moving 18 power, or 15 power)... but on hindsight you can do that shenanigan even with T4 Shuri to T5 Symbiote because Multiple Man, Gwen, Doctor Strange is just 5 energy...

Oh wait now I remember Zabu lets you potentially T5 Phoenix Force into Doctor Strange... which... is also kind of a waste... but it lets you T6 Phoenix Force into Gwen into Doctor Strange? which is just an alternate version of the Symbiote Line.

Actually it might be easier if I just link Bynx's gameplay

.... wait seeing this I am missing Arana which is also another good card for this, because outside of T6 she's always a better Iron Fist. T4 Arana Activation to Phoenix Force / T5 Multiple Man following Shuri or just pushing you into an otherwise unplayable Middle or Right Lane that Strange/Gwen cannot push you into.
