That is a direct quote from the Gwent art book. I don't know who it is implying is the most powerful clan - though if I had to guess I'd say it is in reference to Tuirseach, given that Bran was King of the Skellige Isles and during Bran's reign Eist was Jarl, before becoming King himself and also the King of Cintra.

The full quote perhaps suggests this; "Clan an Craite is the second most powerful in the isles and the most important ally of Clan Tuirseach, longtime holders of the Skellige throne."
