Started DBZ Dokkan Battle.
Drew some badass SSR Gohan, a SSR Vegeta, and SR Third Form Frieza.


Congrats!
The Gohan and Vegeta will be a great place to start your team; the Golden Warrior link will help you shoot off supers a little easier when they're together. Along the same lines, when you start picking up more cards, Vegeta's Prepared for Battle and Frieza's Shocking Speed will do the same thing but better.
We'll be getting the History of Trunks story event soon too (possibly after tonight's maintenance?), which has a farmable SR Trunks that can be awakened into an SSR Super Saiyan Trunks which could give you another good link for your team. SSR INT-type Super Saiyans have been pretty rare thus far, so it'd be a safe idea to grab him if you can handle the event.
Also, with the first anniversary (less than a month away now) come the Gogeta and Janemba summons.

They can be awakened into these:

through some endgame events.
So if you're interested in either of them, it'd be a good idea to save up as many dragon stones as possible.
