whats the point of having so many big creatures if you dont have anything to defend with until you can play them. in my experience, pretty much every modern deck either goes for a kill by turn 6 (aggro), or will have plenty of ways to kill your big creatures as you play them (control or midrange). either get cheaper creatures, or more creature removal spells, as almost every deck I play against in modern summons more than one creature per turn, often from turn 1, while still having removal spells for your creatures.
