Also, would you please consider making the scroll through characters, talismans and the likes more sensitive? Right now I have to swipe with both thumbs for what seems like ages to get to the end of my characters list.
Immunity from a Hellhound or Artillery Dog will protect you for the first round. Other than that, you'll have to either use cleanser characters or immunity talis. Some common cleansers are sentinel Allied Soldier, Mummy Eddie (future power ability), and sentinel Undead Rescuer. You can also use toons who grant immunity with their power move like the warrior Pyro Soldier or the sentinel Corrupt Droid. Kardas has made a great guide for cleansing characters under the "Guides" section of the forums.
Best options are toons with passive team Immunity (Hellhound, Purple Rocket Dog) or passive team Cleanse (Pharaoh Dog King). That's really about it, and I agree that it's really frustrating.
Better variety out of Nautical Souls, but otherwise there's no indication that the value of souls will improve.And will the drop rate for getting new toons ever get better? Seems like I can never pull anything good for pvp.
