1 - you assign them to transformers. Autobots can use Decepticon Weapons and vis-a-versa. Transformers get a big bonus for using their own weapons.

To change weapons: Go to your Team & Squad and click edit. Tap on the transformer you wish to edit. To alter the weapon tap on the one that is assigned and chose another one. If all of the icons light up then you have found the one that matches.

2. I believe that it is linked to the card. Razorclaw and Acid Storm are my favourite cards to use for upgrading.

3. I believe it is linked to your mobage account so you'd need to contact them.
