in the SoC thread, it was brought up that the SoC shard isn't very usable in aether focused decks, and looking around at the shards thus far, they all seem to be less useable than pre-nerf SoG, i have to believe this is intentional.
SoC: useable in denial decks, non-aether focused
SoS: situational use in many decks, limited health/damage to be inflicted window
SoSe: useable in rainbow decks, not reliable means of doing anything, but adds flavor in a fate-egg kinda way
SoR: the
bonus is new, but given the current assortment of time creatures with abilities, is more or less the same as before
SoD: not very sexy, not much changed- minor nerf
SoG: nerfed, less appealing
SoP: situational use, the delayed turn hurts its use in scorpion decks, functions best when using multiple shards in one turn to recoup the damage lost
SoV: while interesting, it is perhaps the most restricted situational shard of all- a deck really has to be tailored to its use otherwise it is easy to ignore it altogether.
so it seems to me that shards are along the lines of nymphs in terms of they look cool and interesting, but they are often less practical/effective than the widely available cards.
