Booster Pack Game

{Judging}Foiled Attack is an interesting card. I like that it works pretty well flavorfully with the idea presented, and using "choose one or both" is a nice idea here. However, according to Adamant Will, the correct wording is "gains indestructible", and speaking of Adamant Will, this card is pretty weak in comparison - Adamant Will is better in most situations as there is no blocking restriction and there's a power boost, while this only gives you flexibility. Overall, a pretty cool card, if not weak.
Radical Mindbreaker is another cool idea, and I think that it's a pretty interesting and fun effect that again, works well within the flavor of the set. The only problem is that it's a weaker Viashino Pyromancer, a card that's already pretty weak, and the condition is pretty hard to meet in some scenarios.
Cipher was an incredibly cool mechanic to bring back that I didn't even consider, and it plays perfectly with the exile-matters theme I set up with the first card, and the flavor of an artifact set that the other two entries added. The card itself seems about balanced to me, especially for a common, so I like it! Great job.
This is not a blue effect, but if this card were black or green, I think that it would have been a pretty cool and interesting card and a nice addition to the set. It's a balanced card, minus the color.
This is a pretty interesting card, as it's kind of like an Altar's Reap stapled to a Diabolic Edict in a way that works well flavorfully, as two creatures get sacrificed and two cards get drawn. It's an interesting idea, and I think that it's balanced, considering it's two 1B cards being put together. Nice job!
This is a fine common, and I think that it's a cool take on using two of green's effects to create a card that makes flavorful sense, much like the last entry. It's also well-balanced, although it's probably a little weaker than similar cards like Elvish Rejuvenator.
This is a pretty weak card, as it's worse than drawing a card most of the time, and drawing from the bottom of your library is something that's pretty annoying when you're in-game. Overall, I'm not sure that I like this effect, especially because there isn't anything else in the pack that makes it into a theme.
I really like this mechanic, as it plays well with the exile theme and works flavorfully. I think that the card is pretty balanced, as I think that it's not broken if you're able to get a 4-drop in your graveyard, and it's not totally unplayable if you manage to exile a 1 or 2 drop. Love the flavor text too!
These are two effects that don't really make sense together, but I like the first one a lot, especially as a tool in draft. I think that it's playable in limited because of the card draw, if not too powerful if you can stockpile your graveyard. Cool idea!
Considering Dark Prophecy exists, this card is undercosted, especially considering it has a 1/3 body as opposed to being an enchantment. That said, it's a cool flavor.
This is a really fun card, and I think that it's a cool method for having graveyard-hate. That said, I think it's too powerful at three mana, as you can likely one-shot an opponent with low life if the game has been going for a long time, and pairing this card with other ones that shuffle your graveyard into your library makes it one-sided and too much.
Imprint is another cool mechanic that works with the theme of the set, and this card seems like a great interpretation of that. I like that you get mana based on the color of the exiled card (although the wording would probably work better as ": Add " style="max-width:100%;"] or one mana of any color that a card exiled with ~ is.") I like that it gives you the opportunity to get access to that exiled card, as you probably wouldn't see it for the rest of the game. Great job!
I'm not sure how timing stuff would work with this card (there would probably be stuff where players try and cast the spell at the same time, and it would be confusing to figure how that resolves), but this is super flavorful, and I think that it's very well balanced and would be super fun to play in a casual / limited format. Awesome job!

Overall, everyone did a great job, but I'm going to have to give the win to fluffydeathbringer for Ancestral Arrival and The Evermind.
