4C Competitive CoCo (Modern)

If the title didn't scare you away, welcome to 4 color Collected Company. You might already see that it isn't all that different from the regular lists running Devoted Druid combo, but the differences that you can see are incredibly important and what I think makes this take a little unique.

For the mainboard, this list is very similar to Brennan Decandio's list that made top 16 in Charlotte. Here are the changes, with some explanation:
I took out one walking ballista for one scavenging ooze because the only real way that the combo gets disrupted is discard and counterspells. If they can get discard to hit a 1-of before you can combo them out, they deserve it, plus this deck is very capable of winning without walking ballista. Countermagic is a problem, but not one the deck can fix easily- thats an accepted weakness, and the current metagame (6/18) makes it a safer choice- scavenging ooze is really excellent because it works well with infinite mana, but it also is great without the combo and a win condition on its own.

I shaved one chord of calling (since we have lots of tutors already), one viscera seer (part of an infinite life combo that I mostly saw as win more), and one eternal witness (probably the most questionable cut, but i felt the cut in redundancy was worth it). Those 3 cuts made room for Knight of the Reliquary- much like scavenging ooze, it provides inevitability by itself. My main goal was to take the dedicated, blistering fast, super redundant combo and instead include threats that work well independently and together with the combo. Knight synergizes by finding utility lands- gavony for value, horizon canopy for card draw, and kessig wolf run if the combo is assembled.

That leads into the lands- they are quite a bit different. Green/White are the primary colors here, but I splashed a single Overgrown/swamp for black and a stomping ground for red. I added one more fetch to ensure you can go get the right shock when you need it and to grow our Knights a little more consistently. I cut a gavony township for a kessig wolf run because Kessig is amazing, but having 2 gavony and a kessig was a little too greedy for a deck with pretty strict color requirements.

I switched Decandios fiend hunter for a fairgrounds warden- they are practically identical cards, fairground is easier on mana.

Now for the spice- the sideboard!

First, the cards that are the same from the regular list:
Abrupt Decay, Maelstrom Pulse, and Path to Exile for various cases where something absolutely must die.
Selfless Spirit for board wipe protection, Qasali pridemage for blood moon/engineered/bogles/etc removal, kataki for affinity/lantern, and aven mindcensor for scapeshift/gifts storm/the mirror match.

My own additions, with their explanations:
Kambal, Consul of Allocation is great against death shadow and any other non-creature deck, notably burn and storm. It grinds in midrange matchups that disrupt your combo easily, and it is a must answer against certain decks. I like it better than eidolon of rhetoric because eidolon only slows the game down, while kambal actively wins the game.
Thalia, Heretic Cathar is also very good into lots of matchups- midrange of any kind, fair decks in general, and especially tron. Between Thalia and the blood moons, you can see that i am pretty concerned with the matchup vs eldrazi tron or g/r tron. Ideally, between the two, plus some removal spells or a super fast combo, you can take the match. Tron is the matchup you side in the most for, taking out most everything that doesnt help the combo.

I hope you enjoy this version of the deck, I've been having great success with it!
