Yesterday I decided to break Magus of the Wheel in legacy with Karn, so naturally I found the Reclaim - Magus to be a match made in heaven. With that being said, I found an annoying bug related to Reclaim and I am not 100% sure what the cause is but I have a hunch.
Basically in a couple of matches, I had reclaim and magus into my hand (not very easy to give a reproduction path how I ended up with both of them in the hand since I also used Behold the Beyond so on occasions BTB would trigger a combo).
Naturally since I had no other creatures on the board, reclaim was not castable.
But then when I put magus on the board, reclaim became castable visually, but the game did not prompt me to cast it, but ended my turn instead.
There were other times when reclaim was castable and it worked just fine, hence why I suspect that magus was into my hand below reclaim. Hence this could lead to the game seeing “ok, I can’t cast reclaim”, then magus would be the next card into my hand so it would get cast, but then reclaim would not be reevaluated.
