We created alot of great content for you to learn how to play online.
We have listed all the relevant rules entries in the description of each video, in chronological order in which they appear, so that you can follow along with the Rules Reference if you want to learn everything in full detail.
The first video also contains a brief introduction to some useful community resources such as ThronesDB (for deckbuilding) and The Iron Throne (online gaming). At the end of the game, there is a short epilogue where we talk about a few things that didn't come up in the game, and we also briefly explain the concept of a Restricted List and the different formats that currently exist in the competitive game.
