The topic title says xBerzerk's UN-UPPED Vampiric Drain Duo Deck (Dark + Aether). Shard of Gratitude is a upgrade isn't it?
GOOD LORD DOES ANYONE READ DESCRIPTIONS ANYMORE!?!
1st:
and the upgraded card itself is entirely optional.
2nd: as for the deck use QI to figure out pillars:
1) total quanta cost
2) divide by five (round if necessary)
3) add that many pillars OR remove something to bring QI down to your number of pillars
Darkness:
2x4+6+4x2+3+1+3x2+3x4=44, 44-4=40 (devourers subtract four by effect)
40/5=8 Pillars! Which means your a pillar short (your mark is technically a pillar)... BUT with fractaling the devourers i feel that that cost is covered up nicely.
Aether:
9x4=36
36/5=6.2
6 pillars are a must for Aether, so just add 1 or change your mark to Aether
PENDULUMS are always an option but should be used carefully because if you spend too much quanta of one element you wont get more until TWO turns later. TheonlyrealBeef has a good point and you should definitely try either a
little more pillars or the pendulums.
