How to defeat the Demonic Wizpig

Use the mighty eagle potion. Wait until you are on the last wave & it takes them all out. I was able to almost beat him without using it, but alas it seems that if you don't have your guys all super pimped out you'll have to finish 'em this way like I did

You can get the paladin for free by going to a random level, select Chuck(yellow bird) and select one of his other owned classes then quicky switch to Red and tap the Paladin, you have to be super quick but then you will have the paladin, and then do the same for Matilda's(white bird) bard, and the blue's class that can send back negative effects, then all you need to do is on the first wave do not attack with the blue's, but use there special ability on each of the birds so when Wizpig attacks it will reflect the purple healing thing back at him and and use the Paladin's Devotion to protect the blue's, and with the purple healing thing on Wizpig attacking him restores your entire health, then keep doing that until you kill Wizpig, and then when you get to Demon Wizpig, KEEP ATTACKING HIM WITH EVERYTHING, as the Blue's will keep resetting his progress on his attack, and Matilda constantly stunning him and prince porky and red doing heavy amounts of damage, and using the rage chili on red whenever you can, he won't even get 1 attack in before he is dead, just remember to finish him off with prince porky, because no bird can defeat him
