Tenth Edition (10th Edition) is the latest "Core Set" for the collectible trading card game Magic: The Gathering. It was released on July 13, 2007, replacing Ninth Edition as the core set of cards for standard tournament play. The symbol for 10th Edition is the Roman numeral "X." As part of their "Selecting 10th Edition" promotion, Wizards of the Coast gave fans the chance to manage a part of the set's brand. The results gave the Roman numeral "X" over the number "10," along with many other card, art, and flavor text choices.

For the first time since Beta, the card borders are black, instead of white like all previous core sets. Tenth Edition is also the first core set, ever, to include legendary creatures, bringing back flavorful relics of Magic's past such as Squee, Goblin Nabob, and Kamahl, Pit Fighter.

Set history
As with the Eighth and Ninth editions of the core set, part of the development process for Tenth Edition included allowing fans to select certain cards for inclusion in the set. This process began in mid-June 2006 and continued for 10 weeks.

Foil cards in Tenth Edition do not have reminder text. Many use the extra space to add flavor text that does not appear on the nonfoil versions. Others, such as Time Stop, simply center their existing text in the text box for added impact.

Mechanics
Core Sets contain only a select number of mechanics chosen from among the many mechanics which have been printed in expansion sets.

The keywords defender, double strike, equip, fear, first strike, flash, flying, haste, landwalk, lifelink, protection, reach, regeneration, shroud, trample, and vigilance are in 10th Edition.

10th Edition is the first core set in recent history to include cards with the Legendary supertype. While the Legendary rule is not explained on the cards, it is explained on the Tips'N'Tricks cards inserted into packs.

10th Edition also reprinted several cards from previous sets with changed rarity.

Chromatic Star, from Time Spiral
Demolish, from Odyssey
Flamewave Invoker, from Legions
Fog Elemental, from Weatherlight

Notable Cards

Pithing Needle A card for one colorless mana that makes four cards from your opponent's deck useless. It is a reprint from Saviors of Kamigawa Set. It fits in nearly every deck because it costs only one colorless mana to play
Troll Ascetic A untargetable by opponents creature card with regeneration ability, awesome. It is a reprint from Mirrodin Set. It can stall Aggro decks or you can go Aggro itself.
Wrath of God A mass removal spell that cleans the board.
Birds of Paradise A 0/1 for one green mana creature, that produces one mana of any color is very good.
Mogg Fanatic A 1/1 for one red mana creature, that can sacrifice itself to deal one damage to target creature or player. It can also kill X/2 creatures. For example your opponent attacks with a 2/2 creature and you have a Mogg Fanatic in play. You block with Mogg Fanatic, put the damage on stack, sacrifice the goblin to deal one damage to the 2/2 creature, damage resolves, his 2/2 creature is dead. A very versatile card. It destroys also Dredge decks nowadays.
Twincast A great copy spell. Copy spells like Lightning Bolt, Hymm to Tourach, Terror, Disenchant, Demonfire, Inspiration, Plow Under, Void Slime. It is a reprint from Saviors of Kamigawa Set.
