Druid as a class is sorta designed to be flexible, so it has a lot of variety as to what it is you CAN do with it.  You could go low to the ground, with a strategy that uses a lot of spells and minions that generate yet MORE minions and play really aggressively.  Alternatively you could go way higher, playing a slower and more control based strategy where you grind out your opponent with value and swamping them with board after board of humongous minions until they can't deal anymore.

If you wanted to go really crazy you could find one of many OTK decks that exist, where you summon minions that make your cheap spells more damaging and throw them all at your opponent's face.

I've been playing for years but I also recently got into Druid, and it's tons of fun!  It has great themes and beautiful artwork.  Have fun!
