So I don't remember the names of all the cards I was going to use for this type of deck but
There's this mirror hall or whatever it's called that allows you tto disregard the legendary rule. This means you can have four krenkos out and simultaneously cast their tap effect each turn. Plus
goblin rabblemaster will be an important asset
Plus that one card that makes it so each creature gets +1/+1 for each other creature of its type n your side of the battlefield.
Last I checked, the deck runs you about 200 dollars, so unless you really want to pound your friends into the ground, I honestly wouldn't suggest paying for it.
