I've been pretty vocal about my stances on this in the past on here, and numerous other social media platforms, but I was unaware it would weirdly upset people that I didn't post it again.
Dude, I barely read the forums and occasionally 60cards, how'd I know what you say on “insert random platform here”. Besides, you might be an exception to this rule, but my observation was more leaning towards a general statement, as I've seen this trend quite often in the past.
You're entitled to your own opinions, but are you sure that is a well reasoned-one?
I mean, the cardpool covers the entirety of HeartGold/SoulSilver-era and Black & White-era. Now the packs are available in the stores, so it is even easier to try for what you need.
The Legacy Format "died" while I was barely playing the PTCGO, so did it stagnate during that time? What I experienced from its creation until approximately a year ago was a Format that would keep you guessing. Something would dominate... but counters would arise so, whether it was days, weeks, or months later, something else was now the top deck in the metagame.
If it did truly stagnate, however please let me know. It is the only way I can learn!
I wasn't talking about card availability. Sure, nowadays it's easier to get your hands on cards like Celebi Prime, Smeargle, Junk Arm, etc. However that wasn't really an issue back then, at least in my experience, as the core of every deck where usually BW era cards that were easy to acquire.
The problem with the card pool is simply, that in the top end you'd see zero development, simply because the best strategies have been set in stone. There is no non EX attacker that can hit consistently for as much damage as Weavile. There is no EX deck that can set up as fast as Genesect. There is no deck as disruptive as Sableye. No deck has as much late game power as Empoleon. [….]
All of the top decks are beyond comparison in the format and without new cards to shake up the meta it's impossible to create something new out of thin air. While you could in theory build a deck designed specifically to counter one of the top decks, you'll likely get eaten alive by the rest of them in the process.
Maybe your experience was slightly different from mine, as it always depends on the environment you play in, so all I can say is that on the top level the meta was set in stone roughly since mid 2017 and hasn't moved an inch since then.
The shadows of the abyss are like the petals of a monstrous flower that shall blossom within the skull and expand the mind beyond what any man can bear, but whether it decays under the earth or above on green fields, or out to sea or in the very air, all shall come to revelation, and to revel, in the knowledge of the strangling fruit - and the hand of the sinner shall rejoice, for there is no sin in shadow or in light that the seeds of the dead cannot forgive...
