I feel that there is a lack of creatures in the "middle" in time, and these work well in giving Time more offensive capabilities rather than waiting and hastening, waiting and hastening. As much as controlling the time in game is effective, Time isn't that well rounded in my view.
I can understand with your reasoning on Time Traveler giving an 'offensive' capability to Time, Anachron Warrior seems to do the opposite - it's completely defensive in that the enemy player NEEDS to have a spell to damage the card, or else the Warrior can be otherwise considered to be an 'immortal' creature (except vulnerable to Thunderbolt, Fire/Ice Lance, Siphon Life, and possibly Mutate/Gravity Pull).
I chose Sekmet as one of the 'mid-hitters', because it's ability can be tied into
as a mono and works surprisingly well with Anubis upgraded or not. Of course, I'm hoping my card idea gets through... ^^;;
