Predalien

Trample, Vigilance, Hexproof, Reach, First-Strike
Predalien must be blocked by a human if able.
If Predalien would kill a creature, instead,
impregnate that creature
(an Impregnated creature can't attack or block,
and gets -4/-1. )
When Impregnated creature dies, create a 3/4 Predalien creature token that's a
copy of Predalien.
