It doesn't appear to be too different than Vow of Duty...
Commander cards: Some kind of one shot token that only effects a lengendary or planeswalker|mybattlefield should work. Lieutenant involves 5 cards tops. We will not break the game using a token work around.
That might work. but cant be sacrificed is another problem. But as a card in my Xtra cards file it may be added without the sacrifice ability. for Lieutenant I am fine with it being legendary creatures just its not official so it should not go into the posted primitive. Technically if the card needs to use a workaround it should not bee added to the primitive in a topic for a set. I just add things that are so minor that the card still works as it should. All the lieutenant cards are in my Xtra cards file if you want the codes for them just update your wagictaco or ask and I will post them as a separate reply.
Doh! Forgot about the "can't sacrifice effect" for Assault Suit.
Commander cards, Clearly I was over thinking them. Yet another example of why we need programmers to help us get more cards in the game.
There are still a few small problems with it. I forgot the Overrun card
They are 230 x 328 with a small 1 pixel black border all the way around.
it is about 26 MB
I still haven't added thumbnails.
Most of the tokens are done. I wasn't sure how to handle the recursive ones like reef worm. Not sure what to do with Wurmcoil engine or any like this that generate 2 tokens?
I still added all these cards in the zip but they haven't been given an ID.
