You can also steal one of his characters and combine with one of yours. It's uncommon, but it's great when it happens.
Steal and sacrifice one of his guys is fun too. You just have to have at least one life gone on your bar to do it.
I put the level at 2200 each and get a pretty good game. Needs sound fx. Needs cost for playing Black Hole (playing the card costs life for number of creatures destroyed or something like that)
Finally got the Impossible badge. Don't upgrade for power if the weapon/item effect is good. Had a level 23 (punisher) cleric item I could have dumpeded for twice the power but it was doing 25% stun. Cleric total atk was 45% chance to stun.
Cool game! Black Hole is too powerful. Needs to have a life cost or something to play. I love stealing and then attacking with then sacrificing the comps characters.
Closing browser during a level 1 boss battle where they are kicking your butt seems to work. It put you back at the start of the battle with the health you went in with. Was facing Lord Marty with 3 Liches that kept stunning my people and a Skeleton, but after 3 tries (browser closing) I finally beat them. Not sure if this will work in the higher levels.
Same as JohnSteel. Got to level 32 and got annihilated out of the blue. Just tried another series to see if closing the browser during a combat with multiple deaths would rerack the battle and it does. Will see if this works during a boss battle.
