Zeph is the only reason highlander decks still be relevant.

Full upgraded Galakrond fast as possible is a much more powerful play than any highlander can do, even a massive high roll with Alex don't recover the game for you.

I play more than 200 games with rogue after expansion released, in 3 variations:

Highlander rogue without invoke cards, highlander rogue with invoke cards and full Galakrond deck with duplicates.

All decks are playable but full Galakrond is the strongest for a large margin, unless the new adventure bring new tools for highlander decks they will be low tier 2 at best.
