So I know it matters which position farseer is in, depending whether or not it gets buffed. That is not what this is about.
What is it about is that, according to the description, it gets boosted if any of your other units (on the field) or in hand are boosted. However, twice, so far, have I seen an opponent who played farseer and played weather effects on my side that damaged troops every turn, and somehow, farseer got boosted. One I remember clearly. Farseer was played, weather. Then Vrihedd Neophyte. Logically, that turn farseer would get a boost because neophyte buffed hand. But the turn after, it boosted as well. And after, and after. What is going on here? Am I missing something? Is it a bug?
