And what do you think of the other cards?
The lore event seems correct in an Haldan deck. A sort of conditional but potentially much more powerful version of secret path.
The dwarf ally feels quite strange to me. Cost is prohibitive if you play for it, effect good but 3 cards discarded are equal to dain effect for a worse payback. Sphere seems wrong as for the most the dwarf discarding mechanic seem set in spirit and to an extent in tactic. Yes stand and fight exist to a reason but still. Stat are good for a non unique character no doubt but the cost is so high if you can't cheat it into play.
