Depends how many syncros you got and, every deck is used in different ways so you should choose
From my experience dueling there has been a few machine synchros that stood above the others. #1 Ally of Justice Catastor reason: Easy to synchro, can destroy certain decks with it's effect plus has a fair attack for a level 5 monster. #2 Power-Tool Dragon Reason: Once synchro you can obtain a random assortment of equip cards you might have in your deck, invincible if it has at least one equip card equipped, fair attack strenght. #3 Armory Arm Reason: Well though Armory arm is weak for a synchro it's effect makes it worth it since it can equip it's self to an other monster so it gains 1000 attack plus any monster destroy by a monster equipped by armory arm damages it's controller's life points equal to it's attack. #4 Genex Ally Triforce / Genex Ally Triarm Now Triforce and Triarm can cause havoc cause of their great assortment of effects that can make either fit into almost any deck depending on the monsters used to synchro for them. #5 Ally of justice light gazer For me it deserved spot #5 cause it is easy to synchro plus it has a fairly high attack that gets higher if you opponents has light monsters in his graveyard. Well that is all. Hope it helps.
I personaly shuffle my deck about 10 or 20 times. I then look through it to see if it is well shuffled and then shuffle it again.
You really could have as many kinds of Pokemon as you want in a deck (so long as you have 4 or less of each individual card), but beginner decks should really only have 1 or 2 types (3 is pushing it). If you're deck is more advanced and is properly structured, 3 or 4 types would be the limit. Beyond this is difficult to manage and usually doesn't work out well.
well, if you are making a deck you should have:60 cards at the most 3 or 2 of the Pokemon can be the same if you want to have a good pile just do 20 of each like 20 Pokemon 20 trainer cards 20 energy cards...
It does not matter how many old cards you have in your deck. Cards should be chosen in relation to the type of card strategy you plan to use. However, you definitely need to keep you deck up to date if you plan to compete against high level players.
