Hi! Im a big fan of control decks so I thought I would pop in when I saw it on the main page.

A couple quick things off the top, the deck has 63 cards right now, definitely need to get down to 60 in the maindeck, also, Cancel is not a standard playable magic card, should definately be replaced with something like Disallow, which is strictly better, or Supreme Will, which is also much better.

You have 14 spells in your removal package across red and black, along with multiple planeswalkers that can act as removal as well, this is maybe a little high for a deck also running counterspells, I would suggest cutting a removal spell or two moving forwards.

I like the counterspell package other than the afforementioned [cancel]'s.

The Nissa, Steward of Elements, is odd, as you can only cast it off your aether hubs and it doesnt seem to be doing what the deck wants to be doing which is grinding wins with planeswalkers or gods. So maybe that can be your first cut.

Evolving Wilds is one of my least favorite lands ever, along with Highland Lake I would try to replace those as soon as possible. The 4th spirebluff and fetid pools are a good place to start, with some Canyon Sloughs also being high on the list.

Sideboard has some interesting choices, Enigma Drake could be good but matches up poorly against the highly played removal right now, lands are not usually sideboard material unless they are utility lands, also, the 2 fragmentize are basically uncastable in this deck so they should go.

Hope this helps, good luck and have fun fellow control mage!

Cancel is standard legal. It was in Amonkhet. If you hover over the card link you can see the undated release. Disallow is still the better 3 mana hard counter though...

Evolving Wilds is a good mana fixer, and you can see it in a lot of high ranking control decks this season. However, it's usually only run in excess of one to two, since drawing multiples is bad when you really want to be drawing lands that preferable tab for colors and don't come into play tapped.
