All creatures have power and toughness.  The power and toughness are found at the bottom right of a card. The left number the the power. The right number is the creature toughness.  If the power and toughness are stars that means they are determined by something else, like the amount of a certain color mana you control.  Power and toughness are main parts to Magic.
		The mana cost for cards is varies for how powerful the card is.  It is found at the top right of a card.  The colored circle represents the colored mana needed to summon the creature.  Sometimes cards use two different colored mana to play.  Often cards have a grey circle with a number in it.  This stands for any extra mana you must play.  Cards with a grey circle and a 0 inside cost nothing to play.
		Abilities greatly change the game of Magic.  They allow you to destroy creatures easier, tap them, or  a variety of other things.  Usually you have to tap the creature and mana to use its ability.  Some abilities you only have to tap the creature to use.  Abilities are useful as long as you use them wisely.
		The most common spells are instants.  Instants are cheap but effective spells.  They can do a variety of things like enhance creatures, revive a creature, or stop all damage.  You can play instants anytime during the game.  Instants can be vary useful because they can save your life or allow you to win the game.  Instants are deadly so watch out.
		Sorceries are less common then instants mainly because they cost more.  Sorceries are powerful and are much better than instants.  But unlike instants you can only play them on your turn.  Sorceries can destroy monsters allowing you to attack them.  Sorceries can greatly change the game.
		The stack is a very confusing part of Magic.  The stack is an action that occurs when someone plays a card but someone else plays a card to counter it.  The card played last activates first instead of last.  Then the card before it activates unless it is counter and then it cannot be played.  It continues on like that until there are no more cards on the stack.  When more cards get played the stack gets very confusing.
