With the new Hearthstone Extension Dr. Bumm's secret laboratory also come new servant properties such as Magnetic. Stephen Chang, Game Designer at Hearthstone, explains the new mechanics in a short video.
In keeping with the theme of the expansion, mechanical servants are back on the rise. Many of the new 'Mechs come with the keyword Magnetic therefore. These can either be played as a normal servant or merged with a mech that is already on the board.
The positioning is crucial when playing: you place the magnetic mech when playing Left from your mech on the board, then the two merge. All values are combined, including special skills such as deprivation of life, ridicule, etc.
If, on the other hand, you play the mech to the right of your existing servants, then nothing happens or the mech is played as a normal servant without merging.
This is demonstrated very nicely in the video and at the latest when Zilliax steps onto the field, most 'Mechs turn into a nightmare.
