So some thoughts on TermiNation Unity:
Her power is a godsend in five-hero games -- I've played plenty as base unity where AOE attacks wiped her bots left and right, leaving me in the lurch while I try to recover, while TN Unity can always be sure to have a bot out. Bee Bot probably benefits the most from this -- if it's already out, then Reconfigure is both damage and environment control; if it's already been destroyed, you can pull it right back out, making her potentially the most reliable environment/ongoing control next to Argent Adept, and less vulnerable to ongoing wipes.
The power is also good in the early game, effectively letting you play a card and still get a double-draw. While the mandatory bot destruction to use the power can be painful sometimes -- you probably want all your bots out -- the extra draw helps to alleviate that a lot. Add in Volatile Parts, and you've got a lot of damage to spread around.
TermiNation unity doesn't make it any easier to get a bot into play from hand, but it's more reliable in the long-game and better at recovering from a board wipe. The only other downside is it seriously reduces the usefulness of Robot Reclaimation -- why pull a bunch of bots back into your hand when you can play them straight from the trash?
