I play pretty much everything but the ones that only include 2 sets cause sometimes they are like alpha + untamed and I don't have enough cards to do much in those!

The wild tournaments I just accept that I'm probably not going to win them but can still win a bit more sps than I spent on the DEC entry fee.

For you I would say stick to the CA only and modern tournaments. Tournaments will be a bit tough without the legendary Rebellion summoners but all of them are set up where if you win a few matches, the minimum reward bracket is still more than the DEC entry fee.

You could also try the GF bronze and Silver version of those tournaments, they tend to pay more than the RF counterparts and have less people in them, making it easier to cash.

I'd say just see how it goes, as long as you win some sps it should be worth it.
