To be able to win a DT or do good in one you need to play FAST !!
Find a deck that suits you, weather its upper / Ambre or montan Hugo it depends on your playing style and once you find the deck you practise with it, trust me you'll get better and better each DT
This is my Deck just in case you need a Start New TD victory
so far i've only won 1 DT with it
I hope it helps you out
Tiny Cuts Modern 2
is pretty nice too and when all those Leaders become penalties this will not die
Also suffers an extra -2 penalty as soon as the new ELO bans kick in. I don't think the bans will make a HUGE difference in the decks you see in DT's, but some new decks may start doing well and some oder decks have a bit more trouble winning w/ the penalties on Ambre, Hugo and Striker.
I think we might start seeing more Rescue players on the top 5 with the new rules.
Once the new bans come in to play
i think junks or even Bangers or juntas might comt into play of DT's
but guys the main thing is to play fast !
so have fun and good luck to all
Check out my new sentinels DT deck 26*
if you dont like Hugo (-2points) you can use Havok
(no problems with Uppers or Montana)
