+1 for the name LOL

You should sideboard Coat of Arms , amazing in any tribal deck, but if you're playing against a tribal deck, they'll take advantage of it easily.

Let's not kid ourselves, we shouldn't try to mimike other archetypes. Collected Company Unicorns (Ccc Collected company corns lol) doesn't offer anything of value. So we should go rogue.

So we ask ourselves, what do unicorns give us? Well, Noble Quarry and Prized Unicorn offer unique abilities (probably never played in constructed tbh.) I'd say the best bet is to abuse that. Regeneration, deathtouch and first strike sound like good options to wipe them out of creatures. You do have some nice ways to to that. CoCo /could/ be an option if you find a way to abuse it as well.

If you can find a way to abuse that 'value' you might have a not poopy deck!:)

Unicorns may not be t1 viable, but they don't have to suck

Ronom Unicorn is definitely sb unless you plan on running Demonic Pactesk stuff

Regarding the first paragraph:

You weren't using CoCo I was just stating for being rogue to not just use strictly worse versions of decks

If my humble opinion can help in some way I'd be happy.

I can see your intention of combining Noble Quarry and/or Prized Unicorn with Basilisk Collar and Darksteel Plate. Appart from destroying the battlefield and if they have gained trample ...well but how you are seeing is not that your deck hasn't got potential but you need a lot of cards in your battlefield and even if you have all there a simple holy day can destroy your strategy... I also think that it won't have a chance against quick red-damage-dealing decks, they can be only beaten easily with good blue counter decks but If you're green you need a quick deck and that's the main problem I see here. In my own infinite it happens the same, not quick enough.

And well another thing if've seen is that well you are highly reliant in few cards.

But keep it up, maybe you can find the perfect unicorniastical combination.
