For the record, yes, I think that being able to hide seals well enough, and activate them at will, would be enough to beat Keiko. If we managed to research
@MadScientist 's idea of Activation Relay Seals, then hid them with Goo Bombs or explosives underneath the arena using HLaM, we could definitely just activate whichever seal is beneath or behind her, either cutting off her retreat or
blowing her up entirely catching her in a Goo Bomb.
I do agree with Roomba about us not being beholden to give spoons. This spoon was freely given, because I was interested.
The trouble now, is feasibility. Which is what everyone was talking about in the first place.
