Hello!

The card Avarice Totem seems to be a bit bugged.

1. Activate Avarice Totem targeting Player B's Sword of Feast and Famine.
2. Expected: Avarice Totem and Sword of Feast and Famine are exchanged.
3. Actual. Player B ends up with the Avarice Totem and also keeps Sword of Feast and Famine. 4 Extra weirdness: After hitting me with the equipped creature, I was forced to discard a card due to Sword, but it ALSO untapped all my lands. Weird.

Thanks!
