1. Check your SRs against the wiki to see which of your cards have the highest max SED. That is, for each category of card (Moe, Babe, and Sexy), rank your top 3 against the absolute top 3 according to the wiki. You want your cards beating ones of the same category at least 90% of the time. (Note: many of the best cards are in the revival gacha, so get as many of those as you can).

2. Select one of the following configurations that best mach your top cards and go after only certain decks. Then, check to make sure your help matches the help necessary to win:
3 Moe 2 Sexy: Go after Sexy; reset battle if your help is not Babe w/ SED > 11,000
3 Babe 2 Moe: Go after Moe; reset battle if your help is not Sexy w/ SED > 12,000
3 Sexy 2 Babe: Go after Babe; reset battle if your help is not Moe w/ SED > 10,000

As a side note, if you could build any of these decks, then select the type of deck for which you most often get the proper help. For example, if a lot of your help comes from Sexy cards, build the 3 Babe + 2 Moe deck.

The vast majority of your losses are going to come from getting the wrong help or losing to a card of the same type. If going after consecutive wins, stay away from Tier 1 unless you have all the top ranked cards at EX +15 or better (Tier 2 is fine with just the best cards at lv 100).
