Your max hand size is 8.
Lets say Time acceleration is the last card in your hand; compare the card draw/quanta to hourglass:
| time accel. | hourglass |
10 | 0 | 3 |
12 | 1 | 4 |
14 | 2 | 5 |
16 | 3 | 6 |
18 | 4 | 7 |
20 | 5 | 8 |
22 | 6 | 9 |
24 | 7 | 10 |
26 | 8 | 11 |
28 | 8 | 12 |
This is extremely expensive. You are better off cutting a number of pillars and adding a few hourglasses.
On top of that, chances are you'll be running a mono or maybe a mark-splashed duo to be able to pay so much quanta-
but the quanta drain prevents you from immediately using the card draw. (and you most likely end up discarding a card even, but thats minor).
The advantages it has over hourglass are not worth the extra cost.
Normally i'd try to compare it to other stuff, but there isn't really anything that comes close.
Precognition is simply a self-replacement, golden nymph is a more complicated hourglass,
and SoBr is both in an element with burst quanta gain, and has the very difficult to compare cost of the opponent drawing cards.
I'd recommend lowering the cost drastically, maybe even 4 would be good.
(Yes, that becomes very similar to hourglass number-wise, which brings questions about it needing to exist).
For protraction, I have a bit of trouble understanding it.
I get that it is some sort of 1-turn full damage adrenaline, followed by a delay on that creature equal to the amount of extra attacks.
Also there's something with an attack buff.
I think that the amount of extra attacks it does equals (7 - atk), but im not sure.
Perhaps you could clear it up?
