For other clans, building a half-deck is much more feasible than a full deck...for Rescue, it's the complete opposite. Hence, let me give you this very important warning: you will need dedication to get a truly full deck of Rescues (it's not worth using Hugo in place of an eighth Rescue card) and you will not see the entire benefits of this build until you've gotten eight Rescues (at this point, every hand will give you the +12 attack bonus), so be prepared for some mediocrity initially.

If you do persevere, however, you will end up with a pretty strong deck that should present a challenge to your opposition. Begin by deciding whether you're patient or not. If you're impatient, Joana is a pretty decent stopgap solution that should not set you back too much until you can afford Bobby. If you're patient, skip Joanna and get Slyde as your first card, one of the two reducers in the Rescue clan. Next, get Ghoub, Glosh, and Lobo, two big guys and a kangaroo that can give you the 2HKO (Glosh's value also climbs higher and higher as you fight tougher opponents and SOA becomes more common). If you haven't gotten Bobby yet, now is a good time to do so. Afterwards, save up a bit for one of the best cards in the Rescue clan, Lea. You really can't ask anything more from a 2-star and that makes her a staple in all rescue decks. Finally, fill out the deck with the cards with Support abilities: Larry and Suzie. With a full deck of Rescues, they will be able to reach their full potential.

It is certainly an endearing process to collect all these Rescues, but I believe the end result is worth it. You'll likely end up spending a lot of time losing and then a lot of time winning as a beginner(8/10).
However, the Rescue clan is not the powerhouse it once was and thus, there are limits as to how much you can upgrade the deck above (Elvira would definitely be integral should you choose this path, as she is the only SOA in the Rescue and can replace Bobby; Anita is also recommended over Lobo). Nonetheless, you can still retain a majority of the cards above and the Rescue bonus is the best in the game, always giving you a chance to win (7.5/10).
