Play fast (= more matches)
choose a strategy:
1) play on 2 hko play as fast as you can
2) play slower but win with more cards (use this when u use allot of low star cards)
2) pills left by ko (max 1 point bonus)
3) life above 12 with ko (max 1 point bonus)
try not to use allot of perm banned cards
16* decks can be pretty viable if you choose the right clans (All Stars and Bangers are amazing for them, as are Piranhas), or you could try the T2 route and use nine 3* characters to give you a 27* deck. Whilst I'm not a tournament player myself, that's usually the advice I've read in topics like this.
Here is a grat deck combination that I got 2nd place with.
5* - Copper
4* - Jackie Cr
4* - Nellie
3* - Oxen
3* - Rubie
3* - Melvin
3* - Harold
2* - Lehane
I got 400 points, which is quite the amount in DTs,
I got 408 with a Hugtana when Hugo wans't perma banned also.
2 hit Ko = fastest way = more points.
When done battles spam the enter button to get more time.
Try to out smart your opp quickly
Basically that wins you DTs.
Uppers are by far the best for two hit combo techniques, mainly because they have two 3* cards with 6 damage (Oxen and Rubie), that contribute a lot to KO....
Then of course there is Jackie Cr, who doesn't need any explanation.
But other clans can do well in Type two also but the most popular is Uppers (not fun to play though)
