Hah! Just take a look at my signature! The team I battle with the most and am most proud of is my grass team.
Ferrothorn
With incredible defenses and ability, nothing works better than Ferrothorn in tanking those outrages and ice type attacks.
Sceptile
Sceptile is here to bring special pressure to an otherwise physically attacking team and to get rid of scarfed/fast sweepers like Yanmega.
Jumpluff
One of my main sweepers and bug counters. Sometimes I can get the element of surprise as Jumpluff is underestimated for its sweeping potential.
Here's a battle showing off its sweeping potential!
Breloom
There isn't a pokemon that can change the tide of the battle as quickly as Breloom here. It's a staple on grass and fighting teams alike and there's a reason it's one of the most feared pokemon out there.
Shiftry
Priority is almost a necessity on any team and Shiftry's ability to break focus sashes and strike with a sucker punch is invaluable.
Tangrowth
There has yet to be a single brave bird that has been able to OHKO Tangrowth. It's also my outrage absorber if Ferrothorn falls. It's incredibly high defenses has helped against many teams and I laugh at people's attempt to overpower Tangrowth with physical attacks as not even a 2X boosted fire punch from Draagonite can OHKO Tangrowth, where I'm waiting with HP ice.
There's my team on paper,
and here's my team in action! One of my best battles.
