Here's how the freemium model works. There is one currency in the game, gold. You earn gold from winning battles, pulling off combo attacks, or buying it.
Gold is used for 2 things, buying booster packs which give you random troops and equipment for your army, and equipping a special power to use during a battle.
The special powers are a bunch of random things you can choose from. Each one that you purchase can only be used once and only in the battle you purchased it for. They are relatively cheap to purchase. They range from buffing your army's attack for a turn, a healing AOE, a poison AOE, elemental AOE, and even crazier ones like a giant crab battle that damages anyone caught in the scuffle. They're pretty much like CO powers from Advance Wars if you've ever played that. Not quite necessary, but can help change the tide of battle if done right.
You can build multiple armies with your troops to do battle with. Each army has a strength rating of 1-3 stars with 3 stars being the strongest. When you battle other players, both armies have to be the same star level to battle. So a 1 star army will never fight a 2 or 3 star army. I'm not sure how the game calculates how many stars your army is valued at though. Could be levels, equipment, troop types, or the amount of troops in the army.
The game is completely playable whether you spend money or not. A player who wishes not to spend will never be at a disadvantage against a player who does spend. Since gold is acquired steadily throughout battles, it's just a matter of how fast you want that gold. You pay up front and get the gold instantly, or play a few battles and collect it over time, choice is yours.
There is also the option to permanent double how much gold and exp you earn in battles. They are priced at $2.99 each, and if you enjoy the game it might be worth looking into. But like I said, it's up to you. The game doesn't restrict anything, prevent you from doing anything, or make it unfair to non-paying players.
