Axie Infinity uses turn-based card games as the battle system. The objective of the game is to eliminate all the opponent's Axies from the battle.

In battles, there are a few things you need to pay attention to:

1. Team formations: In general, the formation determines which Axie is going to get hit first. The frontline Axie is generally the tank and is expected to get hit early in the game. The exception to this are buff or debuff cards, which allow players to target another Axies, following the target rules.

2. The attack turns: The attacking order is shown on top of the screen, along with the order numbers. This also may change in-game, depending on buff and debuff cards.

3. Energy:

   1. Arena: you start with 3 energy. At the beginning of each new round, you'll be given 2 more energy.
   2. Adventure: you start with 4 energy. At the beginning of each new round, you'll be given 3 more energy.

4. Cards in hand: Playable cards you've drawn. The energy cost for a card is shown on top left of each card.

5. End turn: When you are done with your choices, this is where you click to enter the battling sequence.

   

6. Rounds: To keep track of which round the battle is currently in. At round 10, the Bloodmoon Curse will start, and at the end of that round onwards, all Axies will receive a 50 HP deduction. Each subsequent round will deduct more HP, 11th - 80, 12th - 110, 13th - 140 HP respectively.

7. Cards in deck: shows the number of cards in your deck at the beginning of the previous round.

8. Opponent's cards in deck: shows the number of cards in your opponent's deck at the beginning of the previous round.

9. Discard pile: shows the number of your discarded cards.
