Hello, and welcome tho the game and to the forum:)
Well the best way to start killing FGs is truly the Rol/Hope deck, so I'll describe you how it works.

You only need 6 upgraded cards to make that deck work (although Lobotomizes up to 3-4 are needed as well), so you can start building the deck as soon as you have that much coins (I think the whole deck costs around 10000 with 6 RoLs)
The 6 cards you need to upgrade are the 6 Photons. Their upgraded form, called Ray of Light, has the same stats as a Photon (1|1 for zero quanta) but they have a very useful ability: Luminescence. They will give you one light quanta every turn, and they count as a light- emitting creature. Note the synergy with Hope (which absorbs 1 damage for each light-emitting creature on your field) and also note that you need no quanta investment to play a creature that will give you 1

every turn(since RoL is free). That's why the deck needs only aether pillars(the pillar/pendulum split is because of Earthquake.)
The deck works in the following way:
1, You play your pillars/pendulums (maybe a few RoLs too, if you have many in hand)
2, Having reached 10

, you use Fractal on RoL. You should have several copies in your hand now (the more the better); play them.
3, You will gain an amount of

every turn based on the number of your RoLs.
4, Having reached 7

, you play a Hope. It will absorb 1 dmg for every RoL you have. That means if you have 8 RoLs, only creatures with attack of 9 or more can hit you. The Hope is also immaterial, which means it cannot be stollen or destroyed.
5, You continue fractaling and playing RoLs until you are safe from harm. For example, if you know that the opponent's deck contains creatures with no more than 10 attack power, then you need 10 RoLs to defend you. (Usually players play 12-13 of them to ensure a fast

accumulation)
6, When you have enough

quanta, you fractal a Golden Dragon and play the copies, inflicting severe damage in one or two turns.
The lobotomizers are needed to neutralize momentum (which ignores Hope) and dangerous abilities like devour, growth etc.
The deck has several variations. Most notably, the finisher creature varies from upped dragon to upped angel to upped crusader.
The deck fails against lots of FGs (mass CC kills your RoLs, fast quanta denial prevents you from fractaling etc.) but can win games very smoothly against others.
Hope that helps, if anything is unclear, PM me or ask here:)
