War Machine Aggression

This goal does a bit of minion killing, and also is built to trigger Jarnbjorn a bunch. War Machine's Missile Launcher and Shoulder Cannon are attacks that can trigger each turn, with Shoulder Cannon being able to keep readying, giving you lots of opportunities to use Jarnbjorn.

Jarnbjorn: With Jarnbjorn, we want to try to to get a lot of physical resources. Quincarrier helps us get one every turn, Audacity can also provide it with a wild resource. Spider-Man is an excellent ally with a physical resource, and Blade, Hulk, and Marvel Boy all combo well with physical resources. Mean Swing is great here with lots of Weapon targets to choose, and while it's a science resource, Fusillade can get a lot use as well with all of War Machine's weapons.

Minion killing: War Machine can get a lot of ping damage all over the place, making him excellent at removing minions. Hall of Heroes, Looking for Trouble, Chase Them Down, Angela, and Hand Cannon all help here.

I used this to beat the Galaxy's Most Wanted campaign on standard, paired with Gamora Justice.
