Lepellier

You have 2 Utopia Mycons in there.

Darksteel Reactor would be another nice win con for this.

20 is all I ever really need for lands, so dropping the rat for a land seems kinda pointless to me, in my opinion. The reason I'm only running 3 Crusaders is that A) They're expensive, B) 60 cards gives me the best bet at hitting anything I may need, and C) They're great, but not exactly necessary. However, you do have a point, and I may end up dropping a Skittles for one.

Corpse Cur would be another good addition to this, as well as some of the white creatures with infect.

Master's Call says Hi! I don't think that the Glider or Pinions are necessary, so you may want to add in the Master's calls and some silver Myr.

You may want to look into Broodmate Dragon.

Unfortunately, Path is no longer viable in Standard, which is why I run Journey. Hero of Bladehold is just a little too expensive for me to want to grab another one or two. I like the white knights for this deck because they're cheap blockers for those pesky infect decks that I see a lot of in my meta. (Also, don't see many blightsteels around). On the other hand, there is a lot of mana-ramp into BSA's and such that I see, so I like having the flying. Great suggestions, but with the meta I run against, not as effective.

Kor Firewalker is always a good choice. You could also do the Quest for the Holy Relic + Argentum armor combo, which also opens up the use of Kor Duelist. I also suggest Arid Mesa/Marsh Flats, so you can hit multiple ladfalls a turn for the lynx.

The best you can do is drop 4 artifacts, and sec them, but that leaves you with no mana.

If you can afford them, Arid Mesas are beautiful for stuff like this.

Not if you sac it away to a Bloodthrone Vampire. :D

Kor Skyfisher might be a slightly better choice there.

I've come to find out that endless horizons is actually quite an awful card... What happens when someone removes your endless horizons? That's right, you lose all of those lands. They stay removed, and there's nothing you can do, you can't put them into play. Nothing.

@Beyond- All are great ideas, but I generally keep my decks in standard.

@Klasper- Thank you. I don't really like Kuldotha that much myself, though it is a generally over-powered card. I just love Goblin Guide more.

Another possible idea would be run black and put in Liliana, so you can pull up a clone shell one turn, then an Eldrazi the next when you play the clone Shell.

Basilisk Collar to put on Triskelion?

I would try to cut the number of different cards down so that you can run some 4-of's and get some consistency out of this. Right now, it seems just like a giant jumble that would be hard to get a uniform result out of. I don't mean any offense by that, but as it is, it would be just too hard to get what you really need.

Blistergrub FTW in a deck like this. I would suggest dropping a few of the more target spells, and add in a few more creatures. Ideally, I'd say get 16 creatures in this deck.

Yeah, trust me, I'd like Primeval Titans for the deck, but due to the price, Wurmcoil's work just fine for now.

I suppose the Devoted Druid + Magistrate combo works really well. I do also suggest though, taking out the Hydra for Channelers so that all of your creatures are druids except for the warcallers. This deck is heavy enough in creatures that he can be a turn 2 5/5, which is pretty devastating.
