Amazones, lavagolemn and sylvan need nerfs.
They give nhealthy gameplay and are too disruptive.
Limit princess/onslaught to 2. Possibly share.
Do something about the "only use backrow and stall till deckout/lockout" gameplay which is next lvl unhealthy and too easy.
Limit rose lover to 2 for sylvans by making it share with an important sylvan card so that it doesnt harm non-sylvan decks that use rose lover.
This would make the meta lot more balanced.
I rarely see SS anymore in ranked now that we have 5k life.
SB can already be dealt with by f.e. flooding the board, killing or negating spellcaster summons. As they need one on the field for f.e. fate and they also need a spellbook in their hand for several spells.
Disrupt their sequences.
Dont see what could be limited without killing the deck atm.
Maybe changes to the grass is greener card?
Until they made the 5k a permanent addition to the game, don't rely on this reduction.
Flooding the board isn't possible with all decks.
Killing Spellcaster don't mean anything as they can bring him back.
Fate can be indeed limited.
