Staff of Defense from LMOP - can it be traded?

I know you can only trade items of the same rarity, and the description in the LMOP mod doesn't list a rarity for the Staff of Defense or the Spider Staff, but I've heard that the original certs for the mod listed both items as being rare (I haven't been able to confirm it though).

There is also a tweet by Mike Mearls that says it should be rare:

Is this enough to allow them to be traded in Adventure League, or is it still a no-go?

I'm pretty sure those items can be traded using the rarity that was printed on the certs, so you'd trade it as a rare. It gets listed in people's available items periodically on the AL Magic Item Trading facebook group, so I think it's pretty safe to trade.
