Akroan Horse would go great in here

Sadly I can't take credit for it. If you want to check out the original deck here it is. If I remember corectly it was changed a few times.

Makes sense. I have some suggestions then since it's artifact heavy: helkite tyrant and darksteel forge. There's also a great combo my friend used for awhile: helkite tyrant + mycosynth lattice

Since this is a rainbow commander, how about command tower

Also, What price range are we going for here?

Is there a card that wipes lots lots of vampires at the same time?

It's been a few years since you made this, so sorry, but I was just looking through "Anti-___" decks and found yours. Meliria does prevent infect, but I'd find a good card to go with her. Maybe phyrexian hydra. I have my own anti infect deck, but I made it budget so it works a little differently.

Gideon and path to exile. The point of the deck is to out last, so maybe holy day or other prevention

Find some cards that wipe out lots of small creatures. Also add some spells like holy day, maybe a tiny bit of lifegain because goblins are all about over running opponents with tiny creature

Not budget anymore. At least, not your usual standard

Cavalry Pegasus will go great in here

Right. I forgot it was red. Sorry

Try Akroma's Memorial instead of Eldrazi Monument. Also, if the deck revolves around Eldrazi Monument, why is there only one of it

You have four Immerwolfs in your mainboard, and one in your sideboard

Seems like a good deck there are a few more cards you could use, but you seem to be going in a different direction. If you want some examples though: Moonmist, Moonlight Hunt, Silverfur Partition, and Mayor of Avabruck.

I'm working on one of these too, but I've never been good at coming up with win conditions could you help me think of one? I could over run them with wolves, but I prefer to have a few options...

You might want Ulrich's kindred in here. Other than that looks good. If you want to check out my wolf deck for ideas, here it is

Maybe blue red

I just realized. It's not standard. When this deck isn't standard anymore I'd add it though

It has a lot of enchantments, so you might want to add some constellation. Seems pretty good though. I made one of these once. You can check it out for ideas.

A few things.
1) why is stonebrow your commander in a werewolf tribal? shouldn't it be ulrich or something
2) Make sure you at least name your deck. If you want it to get more attention for suggestions, then tag it, give it a how to play and/or deck description

Other than that seems good

It was to go against flying decks. Though now that I think about it, it works against angel, dragon, etc. I'll take out the blue though. Also, do you have any ideas for giving creatures flying while staying green (or colourless)
