No that's way you need to do arena and research. You're not going to have a easy time at the first wall. Every difficulty level will give you more cash/viagra but the first wall will take time to pass out side of buying packs. Grinding boxes for cash to do research and hope you can get a good combo to lock the first spot on the map is the only way. The trainer is a good card to use at the start cuz butt plug and marijuana.
p.s. The rarity of the card will add abilities to the combo: common=none/ rare=first character ability/ epic+=first character+item ability so on need to power up or keep common cards unless you're collecting all the cards
