Wow it is luck that I just saw this....Anyways for those of you who are not up to speed on the card game, they have three new types of monsters out the XYZ (Xceed), the Syncro, and the newest form, Pendulums
First up. Syncro Monsters
This is the first extra deck monster made without using polymerization, instead it uses certain monsters called tuners to start out, they are usually level one or level two monsters like this one
This tuner monster is used along with any regular monster to combine their levels and summon a syncro monster of that level, like the "startdust dragon can be made using "junk syncron and one Level five monster.
Next up XYZs
These are the next evolution in summoning,they are stored in the extra deck along with your fusions and Syncro monsters. these don't require a certain monster to summon them, this particular monster only requires two level four monsters to summon to the field, but those two monsters don't go to the graveyard yet. Instead they are overlayed under the monster as overlay units, by detaching one overlay unit and sending it to the graveyard, you can use that XYZ monsters effect.
Lastly the Pedulum monster
These are the newest way to summon monsters to the field as well as the first real addition to the main deck, they are a fusion of a spell and monster card. Nearly every pendulum monster has two effects and a number scale. One for a monster effect, and the other for a Pendulum effect. If these cards are treated as monsters and are destroyed by battle, they don't go to the graveyard, instead, they go face-up in your extra deck to be pendulum summoned later. with this new card type a new card zone has been added to the field called pendulum zones, with these you can summon monsters from your hand as well as your extra deck if you have any in there, these monsters can be summoned normally as monsters but once they are they can't be used as a spell. If a pendulum monster treated as a spell and it is destroyed, it is sent to the extra deck face up to be used as a monster later, when a pendulum zone is being used by a pendulum monster you can't replace it with another monster, the monster you want to replace has to be destroyed first, once a pendulum summon is made you can't use your spells for the rest of the turn though, and vice versa, so plan accordingly to that new rule.
The number scale is used by the pendulum zones to tell you what range of monsters from your hand you can summon. Lets say the high part of the scale is 8, and the low part is 2. You will be able to pendulum summon monsters ranging from level 7 to level 3, afterwards you can summon syncro monsters, XYZ monsters, fusion monsters, and ritual monsters, this new card is compatible with all other previous formats, it is a wonderful and powerful addtion to yugioh and the card game.
