The Corned Beef scroll is excellent in pvp with aoe hack, yes. I farmed it early in the spec ops for just that reason, but sadly it did not work in pvp until the last week or so.
Here's a little guide on how best to use it:
Agent Gear
You want to set your agent up to either get early turns or make sure that he has a high survivability. You also want to make sure that your Banish attack hits all enemies.
But keep in mind you will only be able to bring 2 optional items, since the scroll takes up 1 slot and you MUST have at least 1 other piece of the hunter set in order to activate the Banish attack. I will suggest some good choices here:
- Blaster armor (any) with Phased Frequencies e-iso: The scroll already has 100% chance to hit, and with the e-iso, not even cube or phased effects can avoid being hit. Miss chance is almost non-existant with this setup.
- Empowered Tactician armor with Snappy Service e-iso is also an option, since you can then bring a healing item like the Staff of Asklepios and heal yourself as a quick action in case you drop below 60% health before you can use the scroll. But then you lose phased frequencies and synthetic cube becomes a problem.
- Savant Spear adds a shield to your agent from the start of the match, increasing your survivability (highly recommended, you need to make sure your agent is above 60% health)
- Sattelite Support ignores distraction and disorient effects (highly recommended since the AI will often use Blackest Void on your team in the first round, giving you a 50% chance to hit your own team with the scroll which is instant game over for you)
- Guardian Insignia gives your agent Survival Training, reduces damage taken by 50% while above 80% health (highly recommended, you need to make sure your agent is above 60% health)
- Synthetic Cube / Hex Wand for survivability (20% dodge chance)
- Scroll of Angolob to remove possible debuffs that might cause you to not be able to hit/attack
- Combat Communicator to give your agent a higher chance of going first in combat
- Mystic to avoid nasty debuffs in the first round
- Fist of the Colossus immune to many dots and gives high crit resistance
Basically any piece of gear that increases your chance of not getting hit or to take reduced damage will be your ally here. The goal is to simply ensure that your agent stays above 60% by the time it is your turn, use whatever you have to achieve this.
Supporting heroes
You need to team your agent up with heroes that can help him stay alive and help him gain extra turns so he can use the scroll asap. The later your agent gets to take his turn, the greater the chance that he will be dead or too low on health to use the Banish function.
- Iron Fist is excellent because he can prevent follow-up attacks from enemy heroes, he can heal your agent and provide debuff immunity.
- Nico Minoru / Cable are good supporting heroes because both of them can grant your agent an instant free turn in the first round. I prefer Nico since she is also hard to kill, and tends to be targetted by the AI. An alternative is Dr. Voodoo, but the problem with him is that he can't grant extra turns until round 2.
- Storm with her e-iso, gives entire team 50% dodge chance from the start of combat, good survivability chances
- Falcon provides Survival Training to your agent and the rest of the team, same effect as the guardian insignia and a pretty solid team up
- Groot / Wonderman / Colossus (with alt suit) auto protects against attacks from start of combat, but many stealthy attackers (like Quicksilver) bypass them so they are unreliable, but a decent choice if you lack other heroes
- Quick Silver or Cpt. America with the Skull Thumper e-iso and Knocking A-iso equipped. Both of these heroes will take first turns (cpt. America needs his E-iso to do this). 10% stun chance plus incapacitation on the whole enemy team gives a decent chance of them losing turns, but is unreliable and should only be used if the above options are not available to you.
- Dr. Doom starts combat by applying cower to the whole enemy team every round, 20% chance that their attacks will fail. Not too bad if you lack the other heroes
- She-Hulk Skirn with store bought e-iso (30 gold) has a pretty high chance of preventing enemy attacks right from the start of combat but is expensive and unreliable, again a last-resort choice
