This is the long anticipated DT Guide. I have won DTs in both formats so should know what I am talking about.
These rules apply for both formats.

1.In DT there are two types of decks that generally see great results. The high damaging deck and the low star deck. A High damage deck is one where you will get at least two 6 damaging cards half the time or more. A low star deck in Type 1 Is a deck with less than 23 stars while in Type 2 it is usually a 9 – 10 card deck which is under 27 stars.

2.Normally I say to include these cards but not this time, Damage Reducers, Heal Cards and + Life cards will slow you down. Try not to include them in your deck and if you must then make it 1 Max.

3.Rule 2 being said, Jungo, Pussycats and Sakrohm will generally slow you down and dramatically lower your chances in any format. Recommended you do not use these clans even in half deck.

4.Try and go mono (1 Clan) as this will make your deck stronger. Sometimes the difference between winning and losing is drawing a 3/1 split and not getting the bonus you wanted or needed. La Junta and Montana are good examples for this. That rule only applies for the Low star deck. If you are going for the High Damage deck then using two clans will be the best way. A good example of this would be Bangers with All Stars or Uppers.
