Who's to say that the Reality Hole is malevolent? It has just as much a chance of kicking off a better paradigm as a worse one. Even if it ends existence as we know it, who's to say that's a bad thing? They've got unicorns over there in nonexistence, and all sorts of other cool things!
Neat! Though the rumored backstories of the messiahs explain their playstyles and starting abilities well, I greatly appreciate the room for personal interpretation, as their origin stories are, in the end, legends.
However, despite Red, Black, and Violet's believable origin stories, I feel that White's description sort of overshadows them, being the most shrouded in mystery, open to speculation, and tinged with the supernatural. Though if there's a better way to explain why he has a greater access to miracles, I don't know what it is.
EDIT: Upon watching your True Messiah tutorial videos, it seems that part of my original question was answered, since cards do not appear to be faction-specific (though please correct me if I am mistaken). However, the core of my question remains - are there any mistakes you might expect beginners to the game to commit, such as agreeing on an alternative turn order and playing that way, that may break the balance of the game? Are there any repercussions to playing out of the specified Red-Black-Violet-White order?
Also, when you say "78 miracle cards," do you mean 78 unique miracle cards, or 78 miracle cards total?
