I've been trying to make a competitive team for a while now on Pokemon showdown but whenever I tried I got mah butt whupped. I'm using good pokemon, but I don't know what combinations or strategies to use. Could anyone suggest a team? I've been using these pokemon:
Lopunny
Meloetta
Blaziken
Greninja
Lilligant(drowsy doom)
Froslass
lucario
Mienshao
Nidoqueen
Leavanny
Mismagius
Zoroark
Mawile
Florges
Aaaaaaaand the most important driving force....Gardevoir!!!

Could anyone possibly suggest a good team? I might be able to think of a strategy for myself...
