I'd take out Redra & Uranus personally. In DT the focus should be on cards that can get you the win... not cards that prevent damage. If your playing defensively, your more likely to play a longer game cuz your WAITING to strike... DT is about getting in with that damage and getting your match over with ASAP so you can move on to the next one.
Still 33rd is not bad at all. Hopefully you'll be able to continue improving.
Rage is right you need to play more offence cards.
a good way to win daily tourments is get a 1hko and use it or bluff its good for a bluff cause the other player might waste all their pills
