Need some help finishing up a Tenpai deck... not sure what else I can do with no UR.

Any help here would be much appreciated lol. Only have 10 UR and can use my SR etc. It's my new account so I've done story to get 20/20 for gems, I have no gems left now

I've done the other where u learn about different summoning for 600x gem per for the 2.4k, dismantled etc to get the UR via the life time stuff.

Account is 3 hours old so hoping to get some assistance :)
