Legacy Blue Moon by Senpaiblank
Blue Moon has been a popular archetype in Modern for a while. At this point, it’s kind of obsolete but forever in our hearts. However, Senpaiblank brought their Legacy Blue Moon list to a Top 8 finish in the last Legacy Challenge!
Blood Moon is even more impactful in Legacy than it is in Modern, since often times even the aggro decks are playing only dual lands.
Young Pyromancer, Snapcaster Mage and Jace, the Mind Sculptor are your sources of card advantage, since you can’t afford to splash green for Uro, Titan of Nature’s Wrath. You’ll have plenty of interaction as well thanks to Counterspell, Spell Pierce and Magmatic Sinkhole on top of the usual Forces and Bolts.
Hullbreacher is the card that’s missing in Modern. It’s so good in this format since almost every blue deck plays eight to 12 cantrips and they’ll all become dead draws as soon as Hullbreacher comes into play.
Dack Fayden’s uses are interesting in Legacy. You aren’t really stealing many artifacts, like you’d do in Vintage or in Cube, but you’re mostly using him to improve card quality, or if you draw Squee, Goblin Nabob, you can even net card advantage with him!
Dack Fayden and Hullbreacher are a match made in heaven, since you can target your opponent with Dack Fayden and make them discard two cards and you’ll get to make two Treasure tokens! Hullbreacher is even stronger than Narset, Parter of Veils since they won’t even get to draw the first card in your turn!
