This is meant to make a mill deck possible, without giving the opponent even more spells to cast. Flavorfully, it represents Shallan's...well...repressed memories.

Note: After designing this card, I should probably put flashback in the set.

In a sense, yes. Alternatively, you could have it exile all cards with retrace, or with unearth, or with embalm, or with eternalize, or with dredge...

Haha, true. I went with flashback because I had already been considering it and it's a good fit lorewise, since a good portion of the story is told using, well, flashbacks.

This is somewhat of a color pie quirk, but blue doesn't generally exile stuff from opponent's graveyards - especially not in this gravehate way. That's more likely to be done by / or even . On the other hand, and can cause cards from graveyards to be shuffled back into - or put on the bottom of - their owner's libraries, which is essentially the same thing. It's a novel difference. Going with Grazing Kelpie, I would have this be:

> Target player puts the top five cards of his or her library into his or her graveyard, then put up to three cards from that graveyard on the bottom of that player's library.

Also, you don't mill for players, they mill for themselves. The "may" doesn't seem to be necessary since it uses "up to".

Good point. Also, it gives a downside to removing the cards from the graveyard (if you're milling, you don't want to put cards back in the deck), so you don't do it unless it's necessary. Which is a bit more elegant.

Keeping the "you may" for now because -- even though it is a bit redundant -- it helps distinguish between the two effects. Without it, the spell can easily be misread as the opponent choosing which cards to put on bottom of their library.

Hmm, somehow I didn't notice the relation between milling and tucking on bottom. It's quite interesting. That makes me think of a new wording (Cruel Fate kind):

> Look at the top five cards of target player's library. Put up to three of those cards on the bottom of that player's library in any order and the rest into his or her library graveyard.

Oh wait, that can't tuck cards that already were on the graveyard. It also could evade to anti-mill cards until you have a way to handle them unlike the current variant since those usually trigger immediately upon hitting the graveyard.

Well, whatever.

Instead of "you may" you could go with "of your choice" somewhere in there. I did something similar with Sapphire-Winged Herald to pronounce in that card that the choice is the opponent's.

Great card design. Essentially blue grave hate built into in a mill player bait card.

Hey, thanks!
