G/U/W creature deck

[Nahlej]

I have been trying to work on a new deck to take to my local FNM. I wanted to go with G/U when I saw Vedelkan Heretic, and decided to add white, when I noticed Aven Mimeomancer's ability. Here is what I have so far. Let me know what you think.

27 Creatures:
3 Vedalken Heretic
3 Aven Mimeomancer
3 Cold-Eyed Selkie
3 Sygg, River Cutthroat
3 Lorescale Coatl
3 Jhessian Infiltrator
3 Nulltread Gargantuan
3 Nobel Hierarch
3 Rhox War Monk

10 Spells:
4 Path to Exile
4 Gift of the Gargantuan
2 Flurry of Wings

Land 23:
4 Seaside Citadel
4 Flooded Grove
2 Ancient Ziggurat
2 Wooded Bastion
2 Yavimaya Coast
2 Vivid Creek
2 Vivid Meadow
4 Forest
1 Island

I hope to tune the deck today/tonight so that I can take it tomorrow to fnm. Right now it get's recked by Volcanic Fallout, so I'm going to have to do something to help out my red matchup.

Some comments:

1. That's a ton of 3-ofs. I definitely recommend fiddling with numbers, which brings me to...

2. Gargantuan can be pretty solid, but the tempo loss if they kill it before you attack with it is pretty harsh. I would cut those, honestly, and tighten up numbers on certain things which should be 4-ofs, period. Such as...

3. Noble Hierarch. The only reason to play less than 4 is if you're 2 color and are looking to supplement Llanowar Elves or something. You want the explosive starts Hierarch gets you, and playing less than 4 is insane in a deck like this.

4. Aven Mimeomancer, while cute, doesn't really seem that strong. I mean, for one more mana you get Rafiq, which seems to me to be a clear upgrade. I know you're trying to go a different route with this style of deck, but you can do that with the same shell. After all, I played Cephalid Constable in a Bant shell and it was really strong.

Basically, I think that if you want to play a deck like this, just take the normal Bant shell and add some cards to it. Mimeomancer seems spicy with Rafiq, actually, so maybe try to fit both in or something.

Good luck.
