You are, of course, once again judging this card by current standards rather than the ones that were in play when it was created. I think I've said this already, but that's no way of giving an accurate rate. This card was printed before the pokémon Banette had even been invented. :O What is it with you always giving bad rates, anyway, do you get a kick out of it or something? -.-
lol I agree with the Alter Ego dude - Solarys, you seem to be giving pretty biased ratings especially since you compare the card against specific examples as opposed to the whole format or the standards when the card was released.
Also theres really no need to swear about it.. Even if you do use a '!' instead of an 'i'
Anyway back to the card :\
Gengar Fossil:
Evolves from Haunter. Usually being a Stage 2 isn't the greatest things, but the range of decent preevos are quite a bonus for this card. The Base versions of Gastly and Haunter are both atrocious. But the Fossil/LC versions are quite good choices (Rare Candy is the better option eitherway) since most other versions have a killing [D] weakness.
Yes 80HP is very low for a stage 2. But its a Gengar, not a tank. No retreat cost is great as is the opponent frustrating [F] resistance and the tiny retreat cost.
There was a lot of hype about this card as it has the potential of being able to KO 3 opponents in one turn. (2 by Dark Mind, 1 from Curse). But this is a bit difficult to achieve.
Curse: a very good power (similar to an opponents Damage Swap) but can also act as a pluspower for some easy KOs. This is also cumulative as well as working from the bench for some easy damage throwing. Its EXP version has a similar power that is errated for crossing damage counters over which may upset this card.
Dark Mind: A great fun attack, perfect for taking out benched Baby pokemon as well for free prizes. Unfortunately it is for 3 [P] meaning ER all the way and making this card quite slow. Against a [P] Resistant card you've been pwnt - but usually a Tyrouge could help against this (unless it's Sneasel = GG!)
This card can be either frustrating for your opponent , but the low attack damage, high cost and stage 2 means that its more likely going to set you back. I'd rather use Dark Gengar, but with most having a [D] weakness, its quite a tricky card to play nowadays.
5/10
