Restore the Balance

[K-man]

Substrate: https://www.dropbox.com/s/fpoywctckuttb ... trate?dl=0
A green alien organism has invaded the plate. If not destroyed, it will eventually take over the substrate. Can you get rid of it?
Max cells inserted: 2
Difficulty: Superhuman AI
Cells allowed: All except virocyte
Win conditions: Destroy the green organism. You can keep your solution in the plate as long as it doesn't destroy the others for 200 hrs.

You may post solutions.

Did you solve it?

Sometimes it solves itself.

[K-man]

I know. I think it's a bug since when you reload it it's supposed to be always the same. And no, I didn't solve it.

[Alast]

Then why didn't you say so?

And no, it's not a bug. It's just a premature substrate with a challenge you don't even know whether it's solvable...

[K-man]

It probably is. I almost solved it once.

[K-man]

I did it! A devourocyte species kills the offspring and the initial swimmer dies of starvation.

[Alast]

Does it solve this 100%of the time? Because luck seems the only way to kill the initial green swimmer. And where's the fun in that?

[K-man]

With very strategic positioning, it solves the challenge with a 95% success rate. With less strategic positioning, it has a 80% success rate.

I beat it with 0 cells! Just watch it as it's very likely to die from too much competing cells. In fact a good challenge would be to make it survive.

[K-man]

It has a 50/50 chance of dying off itself. I'll need to fix that.
