But, against a shield that reduces Damage, you need almost twice as many creatures just as fast or you wont make it before you get shut down.
fear shield vs fire shield
fear shield: phoenix will deal 7+6+5+4+3+2+1 damages before become useless (28 damages in 7 turns)
fire shield: phoenix will deal 7+0+7+0+7+0+7+etc. damages 'cause it will die every turn (28 damages in 7 turns)
lava golem, forest spirit gain +2/+2 so it's the same with both shield 'cause the creature will never die or became useless
fire spirit gain +2/+0 so with fire shield it die in 2 turns, instead with fear shield it gorw every turn with 1 atk (so.. endless attack vs 2 turns)
fear shield: crimson dragon will deal 12+11+10+9+8+7+6+5+4+3+2+1 damages before become useless (78 damages)
fire shield: crimson dragon will deal 12+12+12 damages before dies (36 damages)
gold dragon: as you said..
so.. these are the resulting.. the creature that are weak with fire buckler because of the great attack and the low hp will deal with this shield more attack than with the other one
the creature with less attack and more hp or same attack as hp will instead deal less damage than with fire shield
but.. fire shield will kill the creature (and in this game the creatures cannot be bring back when they dies)
this one no, so, they area burden because they are in play but won't deal damages, occpuping in this way enemy creature's space
but, they can use ability (and this is against who uses fear shield) 'because, they can still lobotomize, or gain attack or devour (a devour is not so much affected by this shield eh..) or generate other creatures or generate quanta or else..
fire shield kill them instead, nullyfing everything
they are very similar in the end, like opposite faces of the same coin
however.. momentum and creatures with momentum exists so...
however i play even spell that deal damages, and this shield will not reflect them.. others instead reflect them and are indestructibles
(so they will make impossible for me to manage them..), and yes.. i will even deal 100+ damages in a turn with 4+ spell card.
looking at the big picture i think that the perfect deck will never exist, every one have a weakness or are defeatable with another deck (like a circle)
(and cards may always be unfavorable in a play)
