Absolutely not.
We need to talk about all of the decks at once, while looking at the vault, in order to maximize all of them.
That being said, the goal this round is to drop as many new decks as possible. Don't be predictable.
For instance: the life/death deck? That'd be a good one to take this round.
Now, as for my deck versus entropy, entropy did a lot of things we need to worry about. Entropy took discord in almost every deck, that's something we need to plan for. Maybe I'll take the fire stall with upgraded explosions? Entropy also went mostly mono, with their only duos being darkness, and a little bit of aether. They have that nasty graboid rainbow as well. I'm thinking I should take the deck Hrmmm took last round with a few more creatures. Their thickest deck had 40 cards in it, so I'll have to take 42. With upgraded deflags, it might have a shot.
