Laravel 5.1 Find an item using eloquent

I have following tables.

Users

id

name

Events

id

name

Cards

id

name

Transfers

id

event_id

card_id

An user has many events and cards. An user can accepts cards from other user which he met at an event.A row will be added under transfers table whenever a card is accepted by a user, this row links a card_id with event_id. I am looking for a way to check a card (card_id) is added under the transfers table for a logged in user's event(event_id).

eg:-

auth()->user()->events->transfers->where(([['card_id', '=',$cardid]])->find());

Can someone help me by telling what is the best way to handle above situation using eloquent?
