Zoo list base on older concept, board control with smaller minions in early game and playing big dudes next to small ones - this way it is very awkward to clear your board.

This deck has some new tools from latest expansions/adventures which make it even better.

You fill the board with smaller minions and use cards that take advantage from wide board like  Sea Giant. You fight for board advantage in turns 1-4, around 5th or 6th turn you should be able to play "big dudes". Pressure your opponent, play around AoE  and removal spells.

You should be able to rebuild your board after your opponent clears it. When you have strong board you don't need to play small minions, those are your tools to repopulate the board in the future.

One more thing. Frostwolf Warlord is amazing, this card got forgotten but it works in this deck. I played this deck for some time now and it is always 7/7 or bigger, usually it is 9/9. And with Reliquary Seekers allows to create huge board from few Imps.
