Answer 1

cut it down the lands to 1 or 2 and work with what you have because it is very hard to use 3 mana decks also you need the basis with one or 2 type of creatures determing with what u have 3 run around a 60 card deck and u want to make 1/4 to 1/3 mana and producde it fast also so that your oppent will not be ready

Answer 2

You've got way too many lands..cut down to 23...and cut down to two colors. green and red. And 72 cards is WAY TOO MUCH. Stick to 60.

Let's start with your creatures:

You don't need the goblin matron, and you might not need akkir raider that much. And maybe throw out petravarks and stick in another rider. Deus won't really do much since you probably won't be able to get in 6 damage but it's up to you.

Spells:

Take out the black spells and swap them if you like for things to buff up deus. If you do that, get a set of him and find some space for him.
