Feel free to add me. 1048233. I don't have any spots right now, but if you send a pie, I'll kick an inactive and add you.

As for leveling, I keep at LEAST 100 wildcards of each type on hand at any given time. 100 N wilds, 100 R Wilds, and some combination of 100 SR wilds. In general, I have WAAAAY more than 100 N wilds, so I siphon some of the extras into R wilds. I usually also have WAY over 100 SR wilds since they tend to be common rewards in events and after events. I may or may NOT have a lot of R wilds at any given time, and if I drop below 100, it's almost always in the R wild category.

So why keep 100 wilds on hand? If I get an SEC from the e-gacha, I want to be able to level it to 100 immediately to get its full effect. If I have over 100 wilds for any given type, I'll burn them. As others have mentioned, the first thing I do is sort my cards by Moe. I make sure every M card is at LEAST level 50, both R and SRs. Once I get all my Ms to level 50, I'll spend some on my Sexy or Babe cards.

Sexy cards almost always have the highest Max SED, but they give you almost nothing for the first 20 levels and then pay off major dividends for higher levels. The decision to level Babes vs Sexy depends on whether or not the current event is Elite Guard. In elite Guard, max SED is critical, and I need immediate results. Dropping 10 wilds onto a Sexy card will EVENTUALLY give me a little more bang for my buck, but unless those cards were already high level, they don't give me the instant gratification of Babe cards for an instant SED injection.

If we're in any time OTHER than EG, I'll usually level sexy cards for payoffs later. A few levels here and a few levels there eventually adds up.

But I won't level ANY Babe or Sexy cards (unless they are SECs) until every Moe in that category is 50+. My 'cap' on Moe cards used to be 40+ but you get slightly diminishing returns the higher Moe cards go. You still get pretty good results until level 60, so I can theoretically bump all my Moe cards to 60 and still get decent returns, but there's no rush. Eventually I'll have a period where I have a surplus of wildcards, and I'll bump them all to 55. Or 60. But once they hit 60, they'll start giving a LOT less out per level. And every now and again, I'll get cards either through chance time or gacha. I don't have to level EVERY card manually to 60 since some of them will eventually get a level up here or there.
