Snow Deck Support
The dimir snow deck in standard is pretty decent and fun to play. I would enjoy being able to play it in historic. The biggest card that would help this deck is dead of winter. It would be fairly balanced, we already have 3 drop -3/-3 wipes, but if you played heavy into snow it would give you a payoff to help against goblins/elves, which can win turn 4.
The second card would be blizzard specter, giving evasion and also a blocker against flying decks.
The last card that I don't see making it way into historic, but I would like, is marit lage's slumber. Gives you scry, gives you a large win con, but it still requires you to lean into snow to get the payoff.
If at least the first two were to make it into a historic anthology, I'd definitely be willing to pay for the anthology to have a viable snow deck in historic.
Edit- Slumber is already there! So the other two would be excellent if we could get them!
