Use King of the Swamp depending on what you need. You can send it to the Graveyard to get Polymerization or use it as a Fusion Substitue. It's recommended to have more copies of this card and replace other Fusion Substitute monsters.
Farmed chazz with the example deck dark paladin deck that is listed.
I used a fusion subtitute monster instead of fusion sage since the card can be very difficult/expensive to get.
The rest of the deck is exactly the same.
I farmed him 13 times and failed once by getting unlucky. This deck is not 100% but it is very efficient
The deck can't be 100%, there is always a chance you get unlucky, but it is really low, low enough to make it worthwhile farming him with the deck regardless.
2 notes: In my 13 fights I had no use for dark flare knight, he also dies to the (new?) armed dragon in chazz's deck, so you have to summon him at the very end or you risk losing him, summoning him at the end is also tricky because you have 4 cards you can't discard, and need 3 for the fusion.
If you can summon dark paladin on turn one, it is not always the best play - Chazz can lightning vortex you on turn one, meaning that if the only card you have left after summoning your dark paladin is one of the key damage cards, you can't get the damage bonus. If you have only key cards left in your hand after summoning dark paladin, I see no reason not to take damage on turn one(dont summon dark paladin) to avoid a possible lighting vortex on key card...while you don't lose duel assessment points, this does open up a chance for him to use megamorph, should you not be able to discard a card to cancel it, then dark flare knight would actually be useful. There's obviously a very low chance of the duel playing out like this, but its a possibility. Wether you want to spend gems on getting dark flare knight or not is up to you.
Chazz is perhaps one of the most challenging but his weakness are dragons. I use Buster blader dragon slayer. I suggest using blue eyes and substitute fusions. Try to put as many dragons in his grave as you can then summon buster blade fusion. I got over 10,500dmg with it. It's best to bait out lighting vortex before you fusion summon.
