Hi, here are a few comments/suggestions. I'm just beginning so maybe some of these are explained elsewhere that I haven't seen.
Always refer to same attribute by same name ie strength is sometimes called attack, largeness (would "size" be a better world) is sometimes called hp.
"throttled" is not explained.
confusion with "stacks" and "charges" : a stack is a pile not 1 unit (charge) of a pile.
the "|" in creatures' attributes looks like a "1" and is easily miss-read. ex: 3|-1 looks like 31-1. a "/" or ":" would be better.
"writ" --> "scroll"
skills descriptions that need clarifying:
ricochet : owner's or foe's spell or both? "caster randomized"?
infected : 2 poison?
tidal healing : "without"?
orochi : "if not retaliate"?
lodestone : increase cost of actives (skills) for foe or owner?
EQ, trident : any permanents (not just pillars/pends)
empathic bond : upkeep = 1
per 8 creatures?
siren : "Sing"?
white nymph : heals herself or owner?
Writ of vengeance : 108 charges? if one of owner's creatures dies, all the others retaliate?
reinforce : "push"?
pixie : owner's or foe's deck?
SoFre : chances are cumulative?
scattering wind : re-shuffles hand in deck and redraw same qty of cards?
clockwork golem : attack --> strength
Epoch : silence who?
52pickup : "discard deck"?
psyche metal : foe plays card whether he has quanta or not?
Hope this helps.
