The best (or great) software for online game with friends

[Takhen]

I would like answer to you, according to you, which is the best software to play online with friends

I would love if this software has all existing cards or it is possible to add them with an easy procedure (because I'm not so able with programmation), and I would like a simple graphical interface

The best one for me was cockatrice, but it closed the activity, so I'm looking for something more similar as possible

Advices?

It does not look like Cockatrice completely ceased activities :
