I haven't crafted a single Alvida, I even disenchanted one because I got four of them. I think the map is just amazing. If you're doing well, you just beat the Viking and sit behind the Ward. And if things are going badly, you can try to fight back, because by the sixth round you always have Evolve + if you're lucky, you'll have a Ward left on the board.
