I can't recommend this enough, best deck to start against FGs.
I appreciate the learn curve, this deck has.
You will most likely lose your first games with this as unexperieced player, because you need to get a feeling when to draw extra cards.
So don't damn it after your first 5-10 games, once you get to the point you fully understand this, your results go up.
Yes, im only going for OTK, but its so hard to get all card needed for combo.
I think one important thing to consider playing this deck is when to use hourglass, and there are 2 scenarios where the decision to draw or not matters a lot
Actually there are much more situations where your decision if you draw results in a win or a lose. Sometimes you get your combo 1 turn too early when you drew an additional card in ealy game and sometimes the small damage from momentum or poison kills you because you drew your first shield 1 turn too late.
You always have to consider if you can afford to let your shield chain break for 1 turn or if you can afford to feed 1 shield to PC, etc.
Nevertheless noone can foresee, what RNG gives you, but you can at least keep your chances as high as possible.
I found some sort of the fat version working best for me, since I like the EMs and the shorter Skip-list.
I started with 4 HG + Elixiers + Dragon upped, but later included the upped combo cards, I won with this deck.

I use more pendulums over QP since an early shield + hourglass are so important. I never lost having not enough mana for an element I solely fuse with the Quantum Pillars so more pendulums are more reliable, I think.
