You are probably right about the pendulums it will make it more stable against Earthquakes(if you are talking about half-ing life pillars with life pendulums), air pendulums wouldn't work because life mark, I tested hope 2-3 hopes, but the efficiency is lower in simulator, hope shield, is a good shield in the long term game defence, but weak against a lot of creature control, most fireflys are expendable just for extra damage in early game, combined with skyblitz for a surprise win, what I haven't tested is 1 or 2 miracles instead of thorn caparace and maybe 1 life pillar, that will make you stay longer in the game, but there is a reason I put the other shields in the deck, it goes like this, if you have early eagle's eyes, use thorn caparace for a lot of creature damage, if are running low on hp, rush the bonds and emerald shield, instead of spaming lots of fireflys, I haven't tested neither this: +1 eagle's eyes, - 2 life pillars, - 1 EMbond, +1 animate weapon, +1 air pillar.
But is for you to try, have fun changing the decks, I'm just posting a good Win/Lose ratio decks, if you get a higher win/lose ratio, post which cards did you change and some statistics in the SIMULATOR, remember that other factors are important as well like:
(this is the actual average in my FFQ deck)
Player
Wins: 44
Winrate: 44 %
Average TTW: 14.886363636363637
<- 14 turns is not so long, you don't wanna be stock in the same game foreverEMs: 11
<- 11 Elemental mastersEM rate: 25 %
Computer
Wins: 56
Winrate: 56 %
Average TTW: 12.821428571428571
EMs: 4
EM rate: 7.142857142857143 %
So if you outmatch that, great, tell me how!! hehehe
