Aristocrat decks are a combination of sacrifice effects, reanimating and value creation. Wincons revolve around multiple triggers, either from dying, ETB or cast triggers.
White has many great support spells and permanents for +1/+1 counters theme. Counters theme is often combined with White-weenie or token strategy and turns the small creatures into a formidable force.
-1/-1 counters are an opposite of +1/+1 counters. -1/-1 counter decks use -1/-1 counters as a resource and manipulate them for their benefit. Moving, adding and removing the counters on the right moment can turn the tide of the game.
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.
Dragons, alongside Goblins, are reds primary creature types. Dragons are reds strongest creatures and most of the expansions have some kind of red dragon in them. As dragons are expensive to cast, dragon tribal decks run multiple cost reduction effects and have ways to cheat the expensive dragons on the battlefield.
Angels are one of Magics strongest creatures, and are comparable to Dragons and Demons. Angels are strong, flying creatures, with often static abilities or strong ETB triggers.
Cheating permanents to the battlefield is available in every colours. How the permanents are cheated into play depends on the colours available, eg black uses reanimation from the battlefield and red uses sneaking, meaning the permanent will be sacced in the end of the turn.
