# v5-p2 : Deck Management and NFTs
WILL BE RE-ENABLED v5-Phase2\
In Vrumble, your connections are what let you make a deck of cards.
These decks of cards are what enable you to cast various mystic powers in the mini-games or play the Battle in the Ring - Idle Game.
With each friend that you make you can add them to your deck - up to 9 cards total.
{% hint style="info" %}
For deck management since it relates to On-Chain games to get rewards - each time you 'change your deck' you will need to sign an Avalanche Chain Transaction.\
\
Every time you Follow someone you will need to sign the transaction to save that friend state on to the chain.
{% endhint %}
