This week in the world of Magic finance, the biggest winner was Fable of the Mirror-Breaker which increased 177% to just under $2. Not only has the Saga been on the rise in Standard, but it's showing up in Pioneer and Modern as well as a new twist on format staple Seasoned Pyromancer. Recently some pros have argued that Fable of the Mirror-Breaker might just be better than Seasoned Pyromancer in a lot of decks. As such, it wouldn't be a surprise for Fable of the Mirror-Breaker to continue to see an increase in play (and price) in the coming weeks and I'd be looking to pick up my playset now. If the Saga develops into a true Modern or Pioneer staple, it could be a card that ends up $10 or more down the line.

Meanwhile in Modern, Urza, Lord High Artificer (retro) is on the rise jumping 18% on the week to a massive $75. While the legend does have a ton of Commander demand, its recent increase seems mostly tied to the banning of Lurrus of the Dream-Den in Modern, which has lead to an increase in Urza decks like Thopter Sword Combo. Personally I'd lean towards selling my copies now. There aren't many non-Reserved List cards that hit $75 and those that do are usually reprinted shortly thereafter. My expectation is that Urza, Lord High Artificer (retro) will show up in Double Masters 2 this summer which would likely cut its price in half, at least over the short term. I have a couple of copies I opened cracking Modern Horizons boxes and I'll be buylisting them this week just to be safe. 

Speaking of reprints, alongside Double Masters 2, we have Commander Legends 2 releasing in a couple of months. While the Dungeon and Dragons theme might keep some Magic-flavored reprints from showing up in the set, cards like Dockside Extortionist and the Commander 2020 free spell cycle headlined by Fierce Guardianship are generic enough that they could show up in the set. Much like Urza, I'm looking to sell or trade my extra copies now with the hope being that I can pick them back up later this summer at a discount. While I'm not suggesting you should go tear apart your Commander decks and sell cards that you are actively using, if you've got extras sitting around, the safest move is to dump them now.
