I mean, if the card was any more powerful it would probably be too good, considering it works off of sacrifice it's a very potent addition to a new player's collection, while also having some interesting applications in higher level play. Sacrificing, say , a splitter bot is a huge boon if you can then get it back. Also it works off of any death source, so you can chump block with something with low health remaining, deal a good chunk of damage, then get the creature back, which is nice. Also, Reborn Lucca, need I say more?
Card is a fine addition to the Genesis line up, and just because its not preemptive doesn't mean it's useless vs control decks, quite the opposite.
