Since WC is over going to drop my takes on the meta(in tournament play) since I won't be touching it till NDPL.
The 3 best set up sweepers in the tier, each for different reasons. Volcarona can run about 10 different sets althoughI think HP ground, flame, giga drain is the best coverage. Gliscor and Cress are both super obnoxious to revenge for obvious reasons. If you're looking for a wincon on your team these are your best 3./SPOILER]
Offense is the best playstyle in ND without question. With the surplus of options Its hard for Fat, BU, or stall to ever cover everything. Thats not to imply these playstyles aren't viable I just believe offense is the most consistent.
Noob trap, I don't think these structures are terrible. If you're just starting out in tournaments or feel your opponentisnt good enough to break its a good bring. However, your chances against more established players is slim seeing how linear playing these teams are.
The best removal in the tier. Everything else is either unviable or very mid. Lando is a mention but having your defensive pivot also defog gives big SS OU vibes.
