OK, so overall, the deck is pretty good!! Good job!
First:
You want your mana source pie chart to be the same or pretty close to the mana distribution pie chart. You might want to take out 2-3
Plains and add in 2-3 Islands so they are even.
Second:
Your mana curve is very good except for the
Clone Legion cards. Even though you might think they are very good, they're not! You will almost never be able to cast them, and it will just add more cards to your deck, making more useful cards harder to get.
Third:
You want to keep your card amount as close to 60 as possible. You will definitely want to remove both
Clone Legion cards, and you will probably want to remove other expensive cards, like
Ancient Carp,
Sandstorm Charger,
Aven Tactician, and
Enduring Victory. Also, You will want to take away the
Contradict, and add in a
Cancel to make its cost cheaper, because 1 card doesn't really matter that much. After you have done that, then take away an
Island and a
Plains (because you reduced your mana cost amounts) and you are down to 60 cards, and ready to play!!
Last:
If you tell me the strategy of how you will play this deck, then I can help you a little more.
Hope this helped!
