Upgrade cards and build a good deck
You should end up being a bit only and particular upgrade the cards that you like and strategy to play when you have more cards. Since you can constantly go to the trader and trade ten cards of a lower rarity for one card of a higher rarity level, this is crucial. Ultimately, you will have the ability to trade one Legendary card for a random Legendary card, so with a little technique and preparation ahead, you can build an actually great deck without investing any reality money!
Cards of various rarities will be offered for purchase for credits and you can even get some good Epic cards there! They are quite costly though, so constantly think about the advantages when investing many credits on purchasing them from the store!
Discovering the right balance cost-wise is exceptionally essential. Low expense soldiers ready due to the fact that you can spawn them rapidly and send them in high volumes over to the challenger, however going just with low expense cards may show tough versus a competent challenger which, with one grenade or a well put assistance airstrike can erase your whole team and win the game. My suggestion is to find the ideal balance in between low expense and high expense cards, and go for a typical energy expense in between 3 and 3.3.
