Since you start last week and you can only use 100 DS on the Elder Kai banner, yes you can use those stones there, you have really good cards to raise their super, just remember Black PHY and Buuhan both has farmable SA, so dont use Elder Kais on them.

About what banners you should focus, STR should be your priority, INT seems like a good choice too and TEQ.
