why bother with reliquary tower if kruphix is your general?

In case he keeps dying to cards like Sheoldred, Whispering One or sac effects like Fleshbag Marauder and the hand i have while he is out doesn't just get discarded away and wasted. Once he's gone, with no way to keep my hand around after he leaves its a bit of a waste. :/

He will never die to sacrificial effects because he is never a creature by himself. If they flesh bag marauder you, just sac a different creature

True, i still like it as a precautionary measure. And my mana hardly ever needs any real fixing so im not losing much by having it in here.
