I’ve searched the forums and I have yet to come across a discussion that answers my questions regarding embalming. So I apologize if there is already or discussion of some sort of out this and I’m duplicating it. I am confused as to why embalming not only keeps track of every time a creature is reinforced(by culminatively adding the embalm gems after death of aforementioned creature), but why when you destroy your opponent’s embalmed gem, it respawns at the beginning of their next turn. I understand that the mechanic is to allow you to resummon the creature even after it’s been killed, but with every other ability in the game when you hit their activated gems or they’re gems with countdowns they don’t instantly respawn. So basically the board becomes filled with the gems until your opponent actually has the ability to match it(which when it respawns immediately prior to your match phase can make it pretty easy). It makes that ability 100% guaranteed to be used. With cards that destroy your creatures or cards that copy other creatures stats, it can make the game so annoyingly unbalanced I want to throw my phone. I guess what I’m trying to figure out is if this was the intended way the embalm mechanic was supposed to act? I can’t imagine why a simple mechanic such as that would be made so incredibly powerful and guaranteed to work on purpose. I’ve found myself having huge difficulties enjoying the game, when you don’t stand a chance. Were restricted to using only certain cards to be able to participate in events and unless you spend a lot of money chances are you’re not going to have a lot of the cards necessary to remain competitive. I’ve been playing for a while, a couple months after the game was released, but my mounting frustration overall the stupid implementation of restrictions and unbeatable mechanics has driven me to the point where I don’t want to play anymore. And I’m hoping that embalm issue is just a bug. I’m all for having a second chance to summon a creature for free I just don’t think it should be guaranteed that until you match that gem, it’s waiting there for you. 
Embalm activate gems work exactly like other activate gems. If you destroy one of your opponent’s gems, it does not reappear on the next turn, it will re-appear on your opponent’s following turn (and vice-versa).
An activate token is spawned based on the number listed on the card. Embalm 2 will place two tokens on the field. If there is a triple-stack of Embalm 2 creatures that you destroy, you’re throwing 6 embalm tokens on the field. Same with Prized Amalgam, if you destroy a triple-stack, all three copies go to the graveyard and all three copies will come back the minute another zombie enters the battlefield.
The solution to this block is to disable everything with Cast Out. If you don’t have that card yet then… well it is an uncommon. I use Dovin with Cast Out et. al on 2.1, 2.3, and all of 3.x. Sometimes you have to skip objectives since they are only worth 5 points, whereas a loss costs you up to 50 points.
As long as the critters are in the graveyard, the gems will come back. If the ai pops then with three brake creatures on the battlefield, they’ll be exiled..or kill them twice - there are several options for first strike/prevent damage defenders with amk
Or if you want to be fancy – throw stratus walk on them and disable them with Sandwurm.
I mean Cast Out is uncommon so it’s the easy solution – but SW/SW has flair!
two can play at that game, use scrapheap scrounger.
cheap and cheerful once you manage to discard
some.
(nothing plays back from the dead like a revolving
pair of scrapheap scroungers)

have to agree with steeme on this on the last bosses 3.xxx to hard to avoid all the embalm gems, disable them with cast out or what ever else you have ,because killing them or stopping them from being cast( insidious will or pact of negation) just puts them straight on the board as embalm gems making it all the harder to avoid them. wont be long before the ai gets a mini cascade and you got 3+ monsters to deal with.
We call that deck “fly trap”.
