A typical game will play out like this: Ramp (Iron Myr) Flood the board with creatures (Hordeling Outburst) Cast Zada, Hedron Grinder Draw a billion cards (Expedite) Generate a billion mana (Battle Hymn) Cast more creatures, draw more cards, generate more mana Swing for lethal (Reckless Charge) Mana: Lands & Ramp Lands
And having already played a couple pods of Duskmourn precons, I can tell you that these decks dont mess around
The other two can be improved with effects that give your cards haste like Concordant Crossroads or even just a Lightning Greaves works, although very slowly and tediously on something like Magic Online
The spell doesn't resolve
Once the new Core Constructed format takes hold, only Sets 9 through 13 stay legal, including Fabled, Whispers in the Well, Winterspell, Wilds Unknown, and Attack of the Vine
