T1 DT and T2 DT are two different touraments? Or they are one tourament with 2 different rooms, but with same tourney score?
They are the same tournements, they require different deck format but if you enter Type 1 your score will be competing with players in Type 2
Is there difference in T1 and T2, except that i will meet different card deck setups?
No. The only difference is T2 is 26 stars to 40 (generally, could be higher if your a nut) and T1 is 16 stars to 25.
If i play 2 battles in T1, and then play 3 battles in T2, what will happen with my points in DT?
They will combine. Anyone playing in a DT, any format is all competing for first place so you can score in either. A common tactic is a low star deck to get lots of 25-30 point wins and in the last 10 minutes they switch to a 2HKO deck for quick wins
In what tourament i will get more clintz/credits?
You ge the same ammount of credits no matter what tournement or placing. Always you will get 1 credit and I as I mentioned it is the same tournement ranking, people verse eachother so both tournements get the same clints. You may however be better at type 2 and increase your shot at getting more clints via a better placement or vice versa.
I get DT points when playing in Elo
, while tourney is running?
Yes you do.
