You cant really expect your 14-land, seven Plains plus seven Mountains Boros deck to have consistently good aggro openers or can you
WotC really is pulling out all the stops for this set, and I suspect that the number of good reprints will keep the value of the newer cards a little lower than normal simply because theres only so low that cards like Crucible of Worlds and Omniscence can fall
Even if you don't attack with any creatures during combat, you'll still get a postcombat main phase and Temple of Atropos's ability will still trigger
Visitors will be able to buy, sell and trade cards at the show, as well as take part in tournaments
In the case of the Family Matters Commander deck, you'll get a little bit of everything
It's a ruthless approach that few, if any, could prepare for
