Are you sure your mark is WATER? Isn't it AETHER?
Basing it on the fact that it is supposed to be a half RoL - Hope deck, to even manage to get those 3 aether pendulums AND 2 fractals in a almost 60 card deck, the chances are pretty, preeetty low.
It needs to be water to get those nymph's tears working.
That said, that's too many pendulums, and REALLY unbalanced.
Take 3 nymph's tears out, add more water towers, and get rid of RoL Hope. Fractal, however, is a possibility.
Focus on producing one type of nymph: having more than maybe 2 or 3 won't work efficiently unless you're running quantum towers, or ....never mind. It would never work unless your deck is PERFECTLY balanced/you have a nymph queen out early.
You're trying to play the the best cards you see: this doesn't work. You simply don't have the time to play each and every card, even though you NEED all of those cards.
I suggest you make this a 30-35 card deck instead of the 58 card deck you have at the moment.
First, take out all cards except for water cards and pendulums from one other element. I'd suggest time, life, aether, or light, as they have hard hitters.
*Life needs application of epi to make it a hard hitter, but it does 12 damage*
Second, add filler cards that would compliment your choice of elements.

lobo, fractal, Ulitharid

Fog, Eagle's Eye

Dagger, Steal, Dusk Mantle, etc.

Skull Shield, Graveyard, Plague, Condor

Quicksand (?? I don't really know what cards to play for Earth)

Butterfly Effect, Discord

Steam Machine, Fahrenheit

Momentum, Charger, Titan, Grav Shield

Epi, Bonds, Staff, Thorn Carapace

Blessing, Dragons, Hope (You need to bring in your own creatures though)

Reverse Time, Eternity, Procrastination
Those are just off the top of my head. There are probably more to use, but those ones popped up. Make a duo out of them, or go full rainbow with quantum towers.
10 Quantum Towers, 6 nymph tears, random assortment of other cards, Mark of Water.
