You’re right about the goldoids being annoying. However, I don’t think that will be the strongest part of it. I think mostly people will use this in the front line with some epics that can then sweep like all the assisted all monsters. I’m tempted to say that Canishogun might need a time restriction of 100s from start of battle on that SS but I’d like to see it first.
2 diamonoids > 2 goldoids I think, plus on Dolphreeze those come automatically rather than needing to use a 130TU move.
