Just a little shout out to savage for showing us the website with the preview of M'arrillian
invasion. Without him, I wouldn't have been able to write this! :) I am going to go through each of the five cards that they previewed to us, and explain what they either mean, or how they may affect the game play in the future.
Come on, just look at this card. This is definitely meta game material. This is just another step in creating a meta game that isn't so centered around the underworld. This will find a home in an elementalist pauldrons deck, or many of mipedian decks which will emerge after the release of silent sands.
The ability to set up your attack deck for the next four attacks is a very powerful thing. You will get the chance to completely plan your attack against your opponent. You will almost always get the cards that you need in order to win with the exact amount of damage required to beat him or her. This will allow you to save your strongest attacks for the right time, or will allow you to burn attacks that you don't really need.
This mugic is average. I don't know if it will see much play. It won't see anything in 3v3, but it might see some in 6v6 or 10v10. It is strictly worse than Canon of Casualty, so there isn't much more I can say.
This card introduces a new ability: Stat Fail. From what I can tell, it is if the attacking creature does not have that stat or lower, he will get to deal that much damage. It is an obvious next step in the Stat Check and Challenge attacks. This may improve that value of lower stat versions of creatures.
I saved the Open Doors of the Deepmines and Frafdo the Hero for last because they give insight on each other, and helps explain what Frafdo means.
Frafdo the Hero
Unlike Kolmo, Assimilated and the other Assimilated creatures, this Frafdo has a different name from the original Frafdo, so you can two of each in your deck. Frafdo is something called a minion, which you can tell by that new blue symbol in his text box, and that watermark where his overworld mark used to be. He is still technically an overworlder. If you look at the top left of his card, you will see that his overworld emblem is still there, but he has obviously fallen to the M'arrillian mind control powers. Now look at what the Open Doors of the Deepmines says. This means that the blue symbol means that he can only use his energy gain ability if you have a Chieftain, or something to do with Chieftains.
