Red and blue had enough control style creatures to be able to move away from an entrenched reliance on Isochron Scepter and sub par mass removal and play more dorks
Saving a few mana here and there on Heliod, Spike Feeder, and Walking Ballista is good enough to justify the slight tweaks you have to make to accommodate Zirda
In the case of having too many low-cost cards, youll quickly run out of cards to play
In the case where Gev and one or more other creatures enter at the same time, those creatures won't enter with additional +1/+1 counters, even if one or more opponents lost life this turn
Ensure that the cards are packed securely and will not shift or fall out during transit, and try to have as little open space in the package as possible
BPhillipYork: I like the idea of Ulamog emerging out of Emrakul emerging out of Kozilek, all in the same turn
