Their cost is just a number and by making matches of any colour you get mana towards that number. The top card in your hand is filled automatically as you gather mana and then you have the chance to cast it, while any further mana is collected for the next card and so on. In other words, other than the "affinity bonus" there's literally no reason to pursue matches of a specific colour. I find this bafflingly both anti-MTG and anti-Puzzle Quest.

In game where tiles cascade randomly you cannot expect to run a green deck or any color for that matter and have a chance to win every game. If there are 10 green tiles on the board and no potential to match you're screwed and would likely lose the game. The converted mana cost is designed to keep the game objective while still somewhat sticking to conventions. Sure you could in theory create a 5 color deck but once again you are at the mercy of the tiles and may never get the matches you need.
Now for the deck composition and size, I agree to a degree. You complain about the big monsters that you have hit the field with little guys left to do nothing. To combat this you can change your deck composition to have larger monsters to combat this effect but you're going to be very slow to get guys out there. Unfortunately I don't think there is a perfect solution to this issue.
