The combinations between cards are way too many. They will make more cards in time tho, just think u can use 20char cards and 26item cards, the different decks are 100s of thousands.
2nd 10cards to start with is good enough to make ur personal combos. i was had 100 to 10 win/lose ratio with just my starter deck when i first played this game. Then i thought of random deck!! it was even easier afterwards. Finally as i said at ranked matches u dont play vs any lvl of opponent but between a certain range. bottom line if u dont like the game do as i do when i dont like a game. I dont play it. ;) There is room for improvement but thats always the case :)
obwan:1. Play unranked match, u have same chances till u get 10cards, 2. play with random deck if ur starter choices really sucked, this way u learn all cards skills. 3. once u get 10cards u will have more options to play the ranked matches+ u will can still play with random deck. 4 there is a limit of lvl difference u can play with at ranked matches 5. playing a challenge here and there wont hurt u, u dont have to play all just when u have time to kill. i think thats what OneLoverBoomer wanted to say.
