Indestructible
Every colorless creature (including devoid creatures) you control gains a +1/+1 counter.
{t},{7} Digitize target colorless creature. (Digitized creatures cannot be destroyed by any means, but cannot attack or block. Its abilities and effects can still be used, provided no abilities used sacrifice the creature.)
