Oh hai thar.
The Rainbow Hater could use and obviously like lots of those "Amber Nymphs". I haven't tested yet, but your rainbow hater hates the hating of hating rainbow, but doesn't hates enough. Of course, the BH's you have ATM will allow stalling but won't give you a full denial.
"Hidden" (name to come? I'll call it Fast Pulvy from now on.)
Fast Pulvy isn't... fast?I mean, it gets that pulvy out allright, but it just.. stays there. There is no animate. Your pulvy just stays there. You could maybe cut the SoG's by 1 or 2 and then make a few pends earth pillars, and add a dragon of each element. You'll have enough to play them because the deck is fully upped, and the pends + the possibility of using the earth pillars will speed up the usage by a lot.
"The Weight Just Flies Away"
Probably make a good use of SoR's. They would make it so the pulvy's skill cost is 0, and also take out the need of lots of those Gravity Pends, leaving you open for more gravity pillars and to put more offensive in said side of the deck (Gravity). Another idea could be to make it so that you have more pulvy's and oty's, with SoR's and 3 SoG's with heavy armors to control the board and the Permanent side of your opponent quickly, healing somewhat slowly, but the control you'll get from the board could be enough. I dunno, haven't tested, but it's a good idea none-the-less, but while the strategy is somewhat faster, since it will take control of the opponents board, it might make the deck much slower in a way.
"In The Name of Quartic Control, Halt!" (I'll just call it Quartet.)
Isn't bad, but needs some more attack power. It'll take forever to kill the opponent with only 8 attacking creatures, 5 of which could remain at 0-2 during the whole game.
Again, a SoR wouldn't be bad, and maybe you could try to take advantage of the Sundial's skill by adding a RoL as fooder of light quanta and fooder as.. well, fooder of the oty.
