Rescue is best used alone mixing it with other clan can reduce its potential unfortunately Rescue isn't as hot in ELO like before but it is still easy and cheap to use in format where you can use both Alec and Marco.
Look in the public preset for some deck ideas. I would also like to point out that you use at most 8 cards in your deck.
Single mono decks are good.
mixed/doubles aint that bad either.
but in my opinion, dont make a deck more than 2 different clans as you may get a "singled out card", meaning that the card will be played without any bonus.
and, if you like the whole bonus +8 thing, making a sentinel and junkz deck aint that bad either. and put in hugo as well to give them the ultimate edge.
this is only my opinion and glad to help out
