1) he will not, because he has played all the squids he has, and has 13 quanta (which is enough for the dragon, and FG's will always play the most expensive card, I think).
This makes your other 3 comments null and void due to this being stupid.
NEPTUNE WILL ALWAYS PLAY SQUIDS FIRST, HE WILL NEVER SAVE UP QUANTA IF HE HAS SQUIDS IN HIS HAND.
The only time he would play a dragon before a squid is if he ended up with enough quanta at the end of the round to play the dragon the next turn. Also, and I really have no clue, but let's just assume AI's play cards in their hands like they activate abilities. In order. So the AI starts from one end of their hand and works its way to the other. So if he had enough for a dragon but a squid came first in line in their hand, I think the squid is played. Again, I really have no clue, but it may be like this. But they won't save up quanta unless they have nothing to play.
Do read what I wrote and understand it how I wrote it and not as you want to understand it. I never said anything about what he had already played or how many, all I said was THAT HE PLAYS SQUIDS FIRST. It doesn't matter how much quanta he has after that, the fact is HE PLAYS SQUIDS FIRST.
And for the record, if you have never played a voodoo doll against any FG, then you probably don't know this, so I will let you in on the secret. Typically if I have a voodoo doll out with some basilisk bloods on it and gravity pull, FGs will hold back strong monsters until the voodoo doll is weak, then they play them all at once to kill it. They do this a lot of the time. So even if he had a dragon in his hand, there is no guarantee he would play it. So yes, obviously I am the authority on this type of deck. I know all the little secrets and ways of beating each and every FG with my voodoo deck.
