No, it must be on your field, not in your hand, unless an effect specifically allows it, like Eccentric Boy.
Yes, you can, as a Synchro Summon is a special summon, you can perform a Normal Summon on the same turn as one or more Synchro Summons.
Somewhat, yes. A synchro does not count for you Normal Summon for the turn. This means that you can do multiple Synchro summons in one turn. But if you are implying that a Synchro Summon can be usd for a card effect triggerd by or that needs a special summon, then a Synchro summon will not count. ^That's a bit vague. Synchro Summons will most certainly trigger/count towards effects that look for Special Summons - case in point, Bottomless Trap Hole, which can respond to a Synchro Summon because it is a kind of Special Summon. Special Summon is the default, and then you have special types, like Fusion Summon and Synchro Summon. Anything that looks for a Special Summon, will trigger from any of those. However if it only triggers from a Synchro Summon, then only a Synchro Summon will do, not a regular Special Summon.
Generally, no. Game mechanics only permit a player to Synchro Summon on their own turn. The only exception to this rule is the Urgent Tuning card which can be activated during your opponent's Battle Phase as well as your own .Urgent TuningAttribute: TRAPProperty: NormalActivate only during the Battle Phase. Synchro Summon 1 Synchro Monster. (Send the appropriate Synchro Material Monsters to the Graveyard.)Now you can because since there was a new form of synchro summoning call accel synchro which allows you to summon one when it your opponents' turn at anytime on that turn but you must have the requirements on the field first before doing an accel synchro summon.
No, unless an effect specifically says otherwise, the Synchro Components must all be face-up on your side of the field. Eccentric Boy is a Tuner who when used as a Synchro Component, the other monster is one monster from your hand.
An accel synchro summon works when you tuner your synchro monsters with a synchro tuner monster, creating a more powerful monster. There is only one of these monsters (as of December 13, 2009) that exists. But the number will grow. Hope this helps! :) A second form of an accel synchro summon works is when you have a synchro monster, you can use two tuner monster to accel synchro it or in other words double tuner your monster to form a new one stronger version of it.
Synchro Monsters are the newest type of Monster Card. Their color frame is white and include "/Synchro" next to their Monster Type. They are included in the Extra Deck (formally known as the Fusion Deck) along with the Fusion Monsters (Note that with the release of Synchro Monsters, Konami has placed a limit of 15 cards in an Extra Deck. This means that you can only have a combined total of 15 Fusion and Synchro Monsters in your Extra Deck).You must Synchro Summon a Synchro Monster to place it on the field. To Synchro Summon a monster, you must have one Tuner Monster and one or more non-Tuner Monsters face-up on the field. The combined Levels of the Tuner Monster and the other monsters you wish to use as Synchro Material Monsters must equal the Level of the Synchro Monster. Once these requirements are met, you can send the monsters to the Graveyard to Synchro Summon the appropriate Synchro Monster face-up onto your side of the field (this is treated as a Special Summon as well). It is important to note that the Tuner Monster and the other Synchro Material Monsters must be FACE-UP on the field. Almost always, you cannot use more than one Tuner Monster in the Synchro Summon (except in the case of XX-Saber Gottoms).For more information regarding Synchro Monsters, click the first "Related Link" below.For more help on how to Synchro Summon, click on the second "Related Link" below.
Synchro Summoning is the process by which Players send, usually, a Tuner Monster and one or more non-Tuner monsters to the Graveyard from the field while they are face-up. This allows you to Special Summon one Synchro Monster from your Extra Deck. The combined Levels of the Synchro Material Monsters must be equal to the Synchro Monster itself. You can only Synchro Summon during your Main Phases (except with the card Urgent Tuning). This process is similar to the coined term, "Contact Fusion". Note that some Synchro Monsters may require specific Tuners or non-Tuner Monsters.For more detailed instructions on how to Synchro Summon, you can choose the "Tutorial" option in the World Championship Mode, or click on the "Related Link" below.
Synchro Monsters can be summoned from the Extra Deck (formally known as the Fusion Deck) by a Synchro Summon.A Synchro Summon can only be performed with one Tuner Monster and one or more face-up, non-Tuner monsters you control (with XX-Saber Gottoms as the exception, who can be Synchro Summoned with more than one Tuner Monster). You can tell if a monster is a Tuner by looking at the card type and seeing "/Tuner" next to it. For example, you can tell Junk Synchron is a Tuner since its card text shows "[Warrior/Tuner]".In order to Synchro Summon a Synchro Monster, the Levels of the monsters used must equal the Level of the Synchro Monster. For example, Gaia Knight - the Force of the Earth is a Level 6 Synchro Monster. That means Junk Synchron, a Level 3 monster, would need a monster(s) whose Level equals 3 to Synchro Summon that Synchro Monster (or any other Level 6 Synchro Monster for that matter). Once you have met the requirements, you can send the monsters from the field to the Graveyard and Synchro Summon the Synchro Monster (this still counts as a Special Summon).Just remember, unlike Gaia Knight - the Force of the Earth, who doesn't have any specific requirements besides a combined Level of 6, some other Synchro Monsters do. Some require specific Types, Attributes, Archetypes or monsters to be used.
Yes you can. You may perform as many Special Summons (Synchro Summons are Special Summons) in a turn as you have the resources to do so, as well as your one-per-turn Normal Summon/Set. You can do them in any order, either before or after your turn Normal Summon.
You use it to summon a Fusion Monster, which has listed as one of its Fusion components, a Synchro Monster. For example, Dragon Knight Draco Equiste has '1 Dragon-type Synchro Monster' and '1 Warrior-type Monster' as material. So let's say you have a Black Rose Dragon in your graveyard and DD Warrior on the field. You activate Miracle Synchro Fusion, and then when it resolves, banish Black Rose Dragon and DD Warrior, and summon Dragon Knight Draco Equiste.
Stardust Dragon is Synchro Summoned, which does not require the Player to discard any cards. To Synchro Summon Stardust Dragon, you must have one face-up Tuner monster and one or more face-up non-Tuner monsters on the field. The Levels of the Tuner and the non-Tuner monster(s) must equal 8 exactly. If all of these requirements are met, you can send the monsters from your side of the field to the Graveyard to Synchro Summon Stardust Dragon from your Extra Deck.For more information on how to Synchro Summon, click on the "Related Link" below.
The same way as any regular Synchro monster. You need to send one Tuner monster, and one or more non-Tuner monsters, with a combined level of 8, to the graveyard. Then you can place 'Thought Ruler Archfiend' from your Extra Deck into play, as a Synchro Summon.
