2)Reverse Time/Rewind: I find nothing more aggravating then having a monster that you've played RT'd THEN having to waste your next turn re-drawing it THEN not having the quanta to play it! Oh and the cost is just a joke. Even un-upgraded it is too easy to play. Either up costs or make the card that was RT'd put at the bottom of the deck, I wouldn't mind that.
3)Fractal: Seriously..this has to be THE most hated card in all of Elements. Because of this single card, it has the ability to create synergy between ANY element. Fractal-trices... fractal-chargers...the list goes on.... Grant it, its playing cost is rather high, but the effect is the definition of OP and worth each quanta. 8 quanta to get up to 8 copies of one card.. That's a quanta a card. I know, people could counter saying that this card is OP by saying, " But it drains all your aether quanta!" .... When the opponent has 3-4 aether pillar(tower)s it doesn't really matter since normally fractal is the only thing aether in their deck.. I'd say limit the number of cards that can be created AND increase the cost. On top of that, keep the fact that it drains your aether quanta down to 0 after being played.
Somehow I find those two explanations quite contradict each other. You state that you don't want your creature back after it is rewound, so I guess you'd prefer to draw a pillar so that you actually have quanta to play your creatures.
On the other hand you are against the most expensive card in the game (eg. fractal+8 pests = 8
+ 16
= 24 :quanta total) which is even more expensive when playing eg. fractal-chargers or fractal-dragons.
With fractal you have an abundance of creatures, but the main problem is you don't have the quanta to play them all and you need to use special creatures like LoR or pests to gain quanta faster, but still fractal is easy to counter with mass creature control (if creatures cheap and low on health) or with quantum denial in case of fractal-charger, fractal-dragon or anything similar.
Fractal is a powerful card, yes, but it has enough of disadvantages that all fractal decks can be countered in one way or another and if you look at some of the trial battles you will see that fractal decks often lose to non-fractal decks so they are in fact not any better than other decks.
As for rewind, it might be very irritating, but in fact it's not overly powerful. A lightning can kill most creatures for the same cost, a gravity pull also. Against rewind you should try playing your cheaper creatures first (if you can) and more expensive creatures when you have more pillars in play and then it will be more of a nuisance than a real threat. Also, notice that having 6 rewinds in your deck makes your deck much less offensive, you will keep drawing those rather than dragons or other offensive cards so adding rewinds in fact is harmful to many
decks. It is a wonderful card against flying weapons, growing creatures or dragon-based decks, but against all other decks you would do better replacing rewinds with procrastination, eternity, or some offensive cards.
