Hi GTG forums, first time posting because I wanted to try getting in on the creative processes of unlocking stuff.
I haven't been doing any testing myself, but I wanted to try and throw out some ideas to maybe help with getting the creative juices flowing for other people as well, as I myself have been puzzling over the concepts and clues for the better part of today.
I can't help but feel that the Mecha-Knight team as depicted in the mission card I cannot view is important- and as such, I feel that for this unlock, the order in which the team is arranged is important, with Idealist either in front, or in my opinion more likely, in the very last position.
So I've come up with a few ideas as to how this could work. If we must first "form the body," then I feel it is a reasonable conclusion that at its simplest, "the idealist must be the target of one or more effects from each hero target, then do X" X being something I am unsure of, which I will provide a theory about a little later.
This is my idea at its simplest- something like cleansing downpour from tempest, a construct from cosmic, some effect from visionary, mass levitation or twist the ether, perhaps? and any beneficial effect from argent adept. But is it that simple? It could be, but I have other ideas.
Going with the theme of a replication of the mission card, it could be "arrange these 5 in the correct order and cause them to discard cards from the top of their deck in a specific order," or "then idealist does X." Or much more complicatedly, a certain set of cards might be needed before Idealist does X. And I have an idea where to start with this.
In Letters Page 46, Captain Cosmic and Infinitor which I was just listening to before getting inspired to start getting my ideas out here, Adam and Christopher are addressing situations in which he blends his own energy and the energy he attained from the death of Infinitor, and Adam drops a very quick, passing mention of Cosmic "Helping Idealist with a Project", Christopher following up with "He also makes a very big sword." [Edit: Timestamp is 1:20:43] This, I feel, could be extrapolated to give the assumption that as a part of my proposed sequence, Cosmic has to use the Cosmic Weapon card on Idealist.
Now, what do I think X is? I have 2 ideas. Either Idealist defeats the enemy with the Karate Robot concept, or activates Floating Head when it has 4 or 5 cards underneath it. The former could also require specifically 4 or 5 fragments underneath, as it could be representative of the completed mecha-knight being made up of 5 parts, or 4 parts from other cards.
Minor but very related tangent, I've also come up with another idea for the unlock that instead has nothing to do with using the mecha-knight team but instead involves a reference to her power. The wiki states that SSVG Idealists's power, "Form the Head"'s mechanic is "Move a Concept from in Play and any cards under it to under this card. The Idealist deals 1 Target X Energy damage, where X = the number of cards under this card. Destroy a card under this card." Replicating this idea might also be a key to unlocking the variant- VG Idealist could also have to be given from 4 other allies that can ongoing cards that move next to her hero card, to simulate the idea of SSVG idealist's power pulling cards under her hero card. For the record, I'm fixated on the numbers 4 and 5, and individual allies and not, say, slapping a million constructs from cosmic on her, because that's not the "point" of the Giant Robot Sentai stuff; the whole team contributes to form the giant robot.
I'm sorry if this leakage of several hours of me puzzling is either ultimately pointless or considered unwanted or a waste of precious screen-space real-estate, but I'm at least happy to try providing my thoughts on the matter.
