Wrapping Rattles

Try to complete the quest as fast as possible. Mulligan for your low-cost reborn minions or Crystology.

Once the quest is complete, annoy your opponent with copied deathrattle-minions like Mechano-Egg or Sylvanas Windrunner.

Spiritsinger Umbra is wonderfull in combination with Sylvanas Windrunner, get another Sylvanas Windrunner and steal one of your opponents minions at the same time!

Val'anyr gets copied with your HP as well, so be prepared to see hammers flying everywhere.
