Need Better Reward System For New Players

I just started playing the game even at tier 40(+premium pass) which I achieved in 2 weeks. But my credits are only 7k. I can't even make myself a single deck with this. Either reduce the cost of common cards(not illustrated cards for that you can make the card cost more). I want to make so many decks, but how will I play with a different deck if I can't make a different deck even reaching the 40 tier?

I think reducing the cost of cards in general is the way or you can simply give at least 20k credits for new players if they grind in a few weeks so that they can make their multiple decks without bore. I got to 41 tier within 2 weeks only playing lostbox giratina and Charizard Pidegeot deck. That is it, Now I am Feeling Very bored😥. Like I wanna invest my credit in so many decks formation- miraidon-flaffy, chien-pao, arceus, lugia, fission Strike, gardevoir, turbo lost box, and so many more. But as a new player, I have to wait over years of playing to get that many credits to play. It's very hard for new players. So We need more credits who work hard in battle pass. Need a long battle pass with 100 tier or something OR a shorter duration with 5x the credit reward.

Thanks for listening I know It's too much I ask but when I think about it after playing so much in a few days with just two decks I build is tough and getting boring at the same time. I might never come back to this fantastic game if leave now. That would be the saddest thing.
