Artifact decks aim to interact and gain advantage with own artifacts by copying them, turning them into creatures and simply create new artifacts as tokens. Artifact decks are very popular and they have multiple infinite loops.
Pirate tribals are creature heavy decks focusing on controlling and preventing opponents from winning with resource efficient interactions. Pirate decks are less combat focused than many other tribal decks.
Treasures are artifact tokens similar to Gold tokens. Treasures have an activated ability to create one mana of any color, by tapping and saccing the token. Treasures are available in every color but focusing on red and green.
Cantrips are spells with a draw effect on them. Cantrip decks are often instant and sorcery spell slinger decks and aim to cast as many cantrips as possible and creating value from the cast triggers.
Mono white token decks aim to create a mass of small creature tokens and then with anthem effects or +1/+1 counter defeat the opponents in combat. White token decks are aggressive decks and aim to flood the battlefield soon rather than later due to the weaker card draw mono white has access to.
