Best cards to get 1000 or 5000 power

Hi together,

I started this game some weeks ago and it´s a cool game for sure. I still read some posts here to get some tips and tricks from the community.

But I asked myself what are the best cards to rent or to buy as a beginner to reach the 1000 or 5000 power to earn some DEC without paying to much credits / DEC for the cards.

I would love to get your comments with some recommendations :)
