Hi,
Your almost there,but you still need to fine-tune this deck.
Here are my opinions
1st- You need to drop down to 60 cards.
2nd- You need to increase your total land count to around 24
3rd- Yes Purphoros will be craZy good in your deck.
4th- Those equipments are bad IMO, cut them.
Let's see if you can make the cut down to 60 cards with 24 lands and I can give you some more advice.
Oh and
Hanweir Militia Captain could be nice here.
good luck
