A side deck is a small pool of up to 15 cards, that you can switch into your deck in between the duels of a match. You have to switch one card out for each you put in, and must revert the deck back to how it was originally before the next match. It is useful because you can put counters to various deck types in there, instead of trying to include them all in your original main deck and possibly slowing it down or making it harder to do its own thing. As an example, take Dimensional Fissure. It might not do anything for your original deck, so there's little reason to use it. However if it is in your side deck, then if you play a deck where it is very useful against, you can side it in after duel 1.
In Match Duels (basically, you're playing best out of three with another duelist) a Side Deck can be used. A Side Deck is entirely separate from your main deck of cards and can only hold a max of 15 cards. After a duel is completed, before the next duel starts each player can look at the cards from their Side Deck and swap them with cards in their Main Deck. Cards included in the Side Deck would be ones to counter and adjust your strategy now that you have seen your opponent's deck in action. You might want to include extra Spell/ Trap removal against this one strategy or remove a card from your deck that doesn't function well against your opponent. In any case, cards taken out of the Side Deck must be replaced with cards from your Main Deck and vice-versa. Once players are done, the second duel begins. If there is a need to go into the third a final duel, each player can exchange cards in their Side Decks again if wanted.
You can only have between zero and 15 cards in your Side Deck.
During a Duel, your side deck is untouchable, nothing can affect it. Only in between the Duels in a Match, can side deck cards be switched with main deck cards, and therefore allow them to be used.
Although some Decks do have advantages over others, no Deck is completely unstoppable. Each Deck has specific weaknesses and disadvantages, usually in the form of counter-strategy cards. These cards are usually stored in the Side Deck in a tournament, so that a Player can change their Deck to suit their opponent.

The player may use these cards in his or her main deck during all games after the first one in a match.The deck and sideboard must each be returned to their original compositions before the first game of each match.Restrictions on the composition and use of a sideboard can be found in the deck construction rules for a particular format type.
The Extra Deck is just the new name for the Fusion Deck. It contains all your Fusion and Synchro Monsters. A Side Deck is a group of 15 cards you can swap out in a Match Duel (a best two-out-of-three duel). How it works is after the first duel (or after the second duel if the score is tied), you can swap one or more cards out of your regular deck for the same number of cards from your Side Deck. This helps by adding cards on the spot to counter your opponent's deck.
