Tempest, expansion set number 12 for Magic: The Gathering, was released in October of 1997. Its series-symbol is a storm cloud with lightning bolt.Tempest introduced 3 new rules: "Buyback", "Licids", and "Shadow". Explanations of these rules are quoted from the Wizards of the Coast website, http://www.wizards.com

Buyback
"Instants, interrupts, and sorceries normally go to your graveyard after they resolve. Buyback is a new option that allows you to use these types of spells over and over again by returning them to your hand when they resolve. Each such spell has a "buyback cost" in addition to the casting cost.

If you pay the buyback cost when you play the spell, then the spell is returned to your hand when it resolves, rather than going to your graveyard. You have to pay the buyback cost when you play the spell if you're going to pay it at all.

Returning the card to your hand is part of the spell's effect, so it won't occur if the spell is countered or fizzles against all of its targets. Instead, the card is put into your graveyard."

Licids
"Licids are a type of creature. Licids can become creature enchantments, reside on other creatures for a while, and then revert back to being creatures. A typical licid is represented below:

R(Tap): Enraging Licid loses this ability and becomes a creature enchantment that reads "Enchanted creature is unaffected by summoning sickness" instead of a creature. Move Enraging Licid onto target creature. You may pay to end this effect.

When a licid becomes a creature enchantment, is loses the licid ability and gains whatever ability is listed in the card text. It also stops being a creature and becomes a local enchantment instead. It retains all of its other characteristics, including its name, color, and so on. You still control the licid while it is an enchantment.

Unlike many abilities that move an enchantment onto another permanent, the licid ability targets the creature to be enchanted. If it fizzles against that creature, it will not take effect, so the licid itself will be unchanged.

Generally, the cost of using a licid's ability includes tapping it. This means that when it moves onto the creature, it will be a tapped local enchantment. the enchantment's ability will work normally, though, and the card will untap during your untap phase."

Shadow
"Shadow is a new standard creature ability. It is both an evasion ability and a blocking restriction. Creatures with shadow cannot block creatures without that ability, but can't be blocked by those creatures either. In this respect they are like creatures that have flying but can't block creatures without flying."
