it very easy in elite guard type if you are a old player with over 500 sed and have save up some event ticket, but gambit and coliseum type don´t
in coliseum the sr prize go to top 100 or 150 i don´t remenber well <,< but it have the free coliseum gacha box with 2 sr & other stuff and 1 event ticket for streak winthat you should save to the elite guard
gambit is a bullshit to milk money from players ,it give 1 sr if you are lucky with silver box ¬¬
