So about battling..

what are some good team combinations you guys use?

I'm new to competetive and just got off serebii..

Sure here are some tips that might help you out.

Dont try to be original unless you know what you're doing. (you should have a ratings for 1500 or top 50 on PO, otherwise don't try to be original, alot of people lose because they are trying to play their own style, trust me it doesn't work) If you are not using a scizor, genesect, tornadus-T or weather based team, your probably not gonna get top 10 in this current meta. I dont think I ever seen anyone in top 10 without those pokes, if you ever see anyone in top 10 without the stuff I listed, show me his team, I REALLY wanna take a look at it.

Think offensively- If your team is weak to terrakion, dont try claydol or nidoqueen, those pokemon have no win conditions. Instead you should use your own terrakion and hope it last longer in battle then thiers, or use scizor. Bascially dont think about what walls it, think about what kills it.

yea think offensively stall doesnt work these days ive seen a blissey and chanseycombi but terrakion kills them terrakion doesnt really have any checks but glidcor but then youd use a poke to ciunter gliscor not wall it as allen said

it pains AK a lot to not be able to stall and make others cry, he feeds off tears
