I don't think this card belongs in time.
The ability itself is completely fine, but is there really a reason that time should get direct damage, considering it has RT?
And I'd take RT over this effect absolutely any day. Much cheaper and less situational. And can technically do the same thing (If you can't draw those copies...)
Thematically, okay, it's an ANCIENT warrior, but I don't think that's reason enough.
"It's living, so it belongs in life"
As for the ability, I think it costs a bit too much, but then again, Owl's eye.
...
I'd prefer this as a spell, not a creature.
