This is the old Cleansing version which deemed to be useless because of being too specific.
I like the idea of anti-Undead card but with some general purpose benefit also.

The updated version is definitely better.

Remade it to be even more specific. But you can feed cheap undead to the enemy via black market or something, infiltrating them

But only commons???
I just had a look: The average cost of common undead is ~6 (with max: 14 flesh golem). If you try to "infiltrate", he can even discard it at once... if not, he'll suffer 1-14 tower-damage for 2 turns, 1 uncommon card and once prodx0.

Assuming this card shall be uncommon it is "total crap" at the moment... I'd prefer to use a good common archer (tower-3) that does his job vs. every deck, not only undead... and is simply common ;-)

...to be honest: after you "control" them, your undead opponent will laugh and play the host or cavalry... or the vampire countess (same cost, nice effect :-D)

To conclude: Only useful for tower-crushers vs. undead. Therefore the effect is much too low.

To be fair, this would be effective against most Unliving decks as well. Granted, the easy fix would be to remove Flesh golem from your deck since it's already annoying enough against Holy decks.

And what did you expect from such low costing uncommon?
Dark ritual rare causes 24 tower dmg , costs 15, and lowers all facilities by 1

Complimenting the upper post - Many decks have flesh golem, because of it's nice stats and modes

And about infiltrating - i've managed to give orc regiment to the enemy in some of my games, after which I've played master hunter, now that was fun I tell you. It mostly depends on what type of game do youplay, but you can simply risk in and give the card earlier, and then suddenly draw trigger card via quick\swift or discard. In my dragon deck I populate enemy hand with rare dragons via confusion and pull them back to me with fairy dragon.
