Exactly my thought. Milva is not an elf in Gwent. In the earlier times, I had wasted Waylay couple of times thinking Milva was an Elf. Also, I had planned wrongly that Milva will be counted as an elf for Arelline and had misplayed. Waylay and Arelline will teach the lesson that Milva is not an elf.
Any idea on the board state and situation when this happens to you? I don't think I've ever seen her not come to the party with 5 elves on the board. It's possible it happened and I just forgot though .
Never had any problems with Aelirenn's ability. But I know that sometimes people get confused by the card arts & in fact, those units are not elves (most common mistakes):
Hawker Support (human)
Strays of Spalla (human)
Hawker Smuggler (human)
Pavko Gale (human)
Just to be clear: I'm not saying that @rcontu misplayed or misread unit tags - maybe there is some kind of hidden & rare bug with Aelirenn? The best way would be to have a clear info what units were present on the board, but....
But this... this is gold... this made my day
