Indestructible might be too powerful for this series because there are only a few ways to kill an indestructible creature in this set. Unless I am missing something, Plasma Blast and The Prophecy are the only ways to exile a creature, Life's Exhaustion can make it be sacrificed; Terran Pilot and Mind Control are the only ways to steal it; and there are six ways to make something smaller, Hideous Abberation, Zerg Defiler, Zerg Infester, Infested Growth, Swarm's Momentum, and Creep Snare. Of those ways to make a creature smaller, one 1, the Defiler, has the ability to kill the Battlecruiser but at the cost of 7 other creatures. In the sets that featured indestructible as an ability, they had wither, infect, or had indestructible be very expensive. For example, Terran Battlecruiser to Darksteel Gargoyle: the Battlecruiser costs 2 more, is +5/+5 and trample.
