Keep one of either Slyde/Steve
. Neither one is a huge threat to win rounds, and really you only need one DR in a DT deck, just to dodge nukes when you need. It'll up your star count, but try either Marco, Sledg
, or if you have lots of money, Alec Cr
. You really only need one in your deck to up your KO potential.
Lastly, remember that for DT you only need 13 life in order to get the +2 bp points; so really only one or two life gainers are needed. Switch everything else out for higher damage alternatives, or low star cards that can win lots of battles - these will get you more points in DT.
Another option might be to consider T1, as your victories will count the same, but you run less risk of being greatly outclassed by your opponent's cards. I can get top 100 consistently with T1 even if I'm watching the world cup at the same time because you get a lot of points per battle.
