Well first I arrange the deck so that it's fire>attack card>attack card, for as many as I can. Then once I run out of fire cards, or get close to reaching the cp limit, I'll put in two zero cards, a elixar, some cures (like three) and if I have them spare fire cards.
Then I pretty much go in guns a blazing spamming fire raids, then use the elixar to restore all my cards and repeat spamming all my fire raids.
Once out I rely on the spare fire cards to get a couple more fire raids or firaga's in until those are gone and then I chip away what health he has left with attack cards, using zero cards to break his sleights.
The fire raids should take a good chunk of his health out if you make sure to carry a bunch of fire cards with you.
