As a new player, I would say the story isn't really going to give you many exp cards. You get exp cards from the ember gathering daily quests, and from events. It's easy to use the daily quest to get a jump start for your servants, because the quest gives you so much master exp that you should pretty much always get a master level before you run out of AP, so it'll keep refilling your AP bar and you should be able to spam it. I wouldn't recommend that you spam it too hard, because you will want those free AP refills for some other stuff too. But it can be nice way to get a couple of servants up to level 40ish, so you can have an easier time starting out.
 
Otherwise, I would suggest you play the event right now and get exp cards from the lottery. 50 gold and silver exp cards per box, plus QP and some materials which should be enough to bump some servants up to 30 or 40 before ascension. The first couple of event nodes should be easy enough for even low level players, especially with a strong Saber Alter friend support. Also silver exp isn't bad for early levels servants, it's only later on when they are higher level and the QP and exp costs per level increase that it is better to burn silver exp for prism. There are other tips like only using half the exp required to get to your servants current max level since you can sometimes get a super or great success, which gives 2 or 3 times the exp you invested.
 
In addition, setting a priority order when you upgrade your servants. If it's an efficient servant to raise in a slot of need, level it first. Thus, Kuro and the upcoming welfares like Liz saber and santa alter would take some priority. Outside of that criteria, the best criteria would be to make sure you have something decently powerful in each support slot. That way you can have some class balance. I say support slot because it's the easiest way to arrange servants according to class variety. This is also a handy way of finding out which servant classes you need to fill or back up. Another good general rule is that attackers and dps benefit most from the extra attack and health from being max level. For supports, as long as they have all their talents, being leveled up to 70 or 80 is usually enough and the final leveling to 80 or 90 can wait.
 
That’ s the end of this guide. Hopefully, it would be useful.
