We're still on about that? Alright. Let's talk about some details one by one.
For example, the assertion that Melee > Danmaku, this is fact, because it is mentioned in Remilia's Last Word. That would mean any Danmaku attack is inferior, but Musou Tensei is Danmaku... Now, we have 2 separate spell cards making contradictory claims.
The full description of Scarlet Destiny is:
High speed scarlet. Showing her power straightly without any cheap tricks. In fact she's more of the physical type than magic type, dominating everyone with her superior physical strength. Melee > Danmaku. It's not talking about what Remilia does during this particular Spell Card. In this context, it simply explains her mindset. It's not stating that melee is better than danmaku as a fact, it states that Remilia thinks way. This is even shown in SSiB. Unless someone points out there's a mistake in translation of those lines. Do you see her ever use a melee attack in that card? I surely didn't.
Kaguya's Impossible Request "Jewel from the Dragon's Neck -Five-Colored Shots-", did you know that it grants wishes? You can wish for anything with it.
Full description:
One of the impossible demands Kaguya presented. Each jewel contains stars, and it's said that if you collect 7 of them, it'll grant anything you wish. Note the expression "it's said that". This means it's not presented here as a fact, but as a rumor, unlike the effect of Fantasy Nature.
Yorihime's first special attack against Remilia was an extremely powerful one, in addition to hitting weakness.
Then again using Yorihime, a character who even ZUN refuses to put into any game due to how broken she is, as a comparison to Gensokyo's girls, is not going to have much weight in this argument. To her, summoning Gods may not be considered as breaking the rules or something that's too strong. It's as if she was having a duel against 4 stage 1 bosses, or even weaker. 1 bomb enough to break the enemy spell.
The consumption of energy is meant to show how strong the card is and the amount of energy that user needs to use to do such a move.
If this is true, then it contradicts the notion of powerful spells being allowed to be used right from the beginning. Every new battle in the games starts with both characters with no power. This power required to use Spell Cards is gained through hitting the enemy, grazing or getting hit. In other words, the battle needs to last for a while before anyone can activate a Spell Card.
That sounds like unconsciously attacking to me.
If floating away from "anything and everything" includes consciousness too, then yes. But closed eyes don't necessarily mean she has to be unconscious. It's not the only card where she uses homing danmaku, so having her eyes open may not even be necessary. Several of Reimu's Spell Card activations in Hisoutensoku show her sprite with closed eyes during the spell's effect, not just during FN.
