Yes it is changed, it spawns Rag Nar Roog to each opponent row = 3 damage to strongest opponent unit in each row at the start of each turn. By far most OP Gwent card I ever saw and I really hope they tone it down little before final release.
Btw. nearly each card will be changed for public beta and some core game mechanics too, it is practically new game. Which is cool, because most are very good changes, like new weather system. But in dev. preview there were some clearly OP cards and some totally unplayable, thought they still have couple days to balance them better.
