I think the upped ability is too expensive.
Compare it with the snipe ability
This card's ability costs the same but only does 2.5 damage on average and there is no targeting control on it.
Moreover, the stats on the upped version are pretty pathetic for its cost.
The unupped ability is actually quite different. In some ways, it is the stronger of the two. The reason being that it triggers when the creature is summoned. This removes the possibility of CC counters to it. In essence, you have a spell and a creature wrapped into one.
The ability is weak, though, so it is still not in much danger of being OP, even with fractal or mito combos, because the cost of the creature is quite high relative to the ability effect...
I would actually like to see the cost of the unupped reduced down to 2 or 3. At that point fractal and mito combos would become quite viable.
