Quoted from WaddleJrJr:
I've opened about 4 boxes (3 whole boxes and then some random packs), the boxes were all medium to bad, but I hit a foil Yawgmoth in the random packs.
Sorry to hear that. I had great luck with my two boxes of Modern Horizon
5 Mythics -- Urza, Lord High Artificer, Sword of Truth and Justice, Sword of Sinew and Steel, Mox Tantalite and Kess, Dissident Mage.
3 Horizon Lands including Foil Waterlogged Grove, and two normal ones. Nurturing Peatland and Silent Clearing
As well as Force of Negation, Hagaak, Arisen Necropolis, Giver of Runes, Unsettled Mariner, Force of Vigor, Force of Despair, Force of Virtue, and Cloudshredder Sliver.
Same 3 Horizon lands without the foil
Same five forces including negation.
5 Mythics including sword of truth and justice, Ranger Captain Of Eos, Yawgmoth, Thran Physician, Seasoned Pyromancer, and Morohon, The Boundless. As well as a Foil Snow Covered Island.
Rates included Unsettled Mariner, Cloudshredder Sliver, giver of runes, and Goblin Engineer.
I may buy a couple more boxes and hang tight to see if they become worth anything. Worst case, I crack them later.
