Suicune should be #7.
Celebi/Bliss is a toss up for #8/#9. I'm probably inclined towards Celebi because it was sorta just not given the chance to excel in GSC!
What about Exeggutor? It's arguably top 4 in both RBY and GSC, at least top 5. But how much does it suck in ADV/DP anyway?
I like Cloyster too. I'd place it inside the top ten in both RBY and GSC, it's pretty decent in ADV too.
Unsure about Dnite. But I'm sure that's because I'm not familiar with DP and thus I'm inevitably biased towards 1-3 gens... where it's surpassed by Cloy/Egg.
Forr I think should go behind Cloy.
Raikou is interesting. How good is it in DP?
