Yeah....
Survivor is hard mainly because of the high amount of clintz a person can win. If they didn't have it like they did, then people would be able to earn a ton of clintz and throw the market off balance and make the game even harder for new players.
The best advice I have is to just keep trying at
Survivor. Doing 1 run a day won't earn you much but trying maybe, 10 or 20 times is decent.
Also, take advantage of the DTs. 50 clintz for 1 battle in a DT is pretty nice considering how many DTs there are. You figure, 12 a day. If you only play half of them a day, that's 6. At 50 clintz each, that's 300 clintz. If you play 5 days a week, thats 1500 clintz. For a month, thats 6000 clintz. Just from playing 1 battle in a DT and only counting the clintz from DTs.
If you play enough to get credits in a DT, then that's more clintz and also 3 new cards every 20 DTs which can equal a lot of clintz depending on the cards you manage to get.
It's a nice suggestion though. I'd actually like being able to earn a Credit for getting 500+ in a DM.
