This is AWESOME!! Always loved Godsire. Glad to see him put to good use!! 4 Idyllic Tutor could definitely help you find a Parallel Lives or a Doubling Season for extra lols, right?? XD Either way, definite +1 from me.

Pretty sweet deck. I saw it a while back, but the current version is much better than before. I just playtested it, and combo'd out on turn 4 with Presence of Gond and Intruder Alarm . Unless the opponent had an immediate way to deal with it, then that would've been game. Idyllic Tutor is such a great card to have in here.

To be honest, there's not much that comes to mind to help you, other than instead of Fireball , maybe Banefire would suit better as a Sideboard finisher. It can't be countered or its damage prevented.

I really like where this deck has gone. The tutors for both enchantments and/or creatures are great additions that really pull the deck together (given the multiple combos in the deck). Makes it kind of a toolbox deck. Really great evolution. Great deck Jdvanliew and great job developing it to where it is.

Nice. I would run 3ofs each of Idyllic Tutor and Intruder Alarm

I would also consider switching out Wall of Denial for Drift of Phantasms as it can be used as a tutor for your Staff of Domination

2x City of Brass might be helpful as mana fixing as your mana base is a tad stretched.

You do really need to work on your sideboard, as right now it just seems to be stuff you would swap out for in certain situations, but largely doesn't address any of the decks weaknesses against the meta.

Otherwise...Nice variation on Dave's deck!

Eh. To each their own as far as Mana Confluence over COB. Personally I would rather have the one that I can prevent the damage. But to reach their own. As for your sideboard, you should start focus on making sure you have answers to each archetype. Control, Combo, Aggro and Midrange for starters. Protecting your combo is key. Speaking of which again I repeat... As Intruder Alarm is your key combo piece. Having only two in the deck (even if you have tutors) seems imprudent. Might also consider Vent Sentinel

Just as an example... this is a defender combo deck. You are basically hedging on a strategy of blocking early threats until you can get your combo off. (It's not a bad strategy, I utilize it as well in deck The Source Wall)

A single card like Earwig Squad can completely neutralize and neuter your deck simply by being played. You need to have your key combo enabler be at the VERY least a 3 of, and you need to have means of countering a combo hose, and even proactively being able to prevent them from being played. Thoughtseize Duress etc.

Your entire deck is focused on getting your combo out, but you have no prevention or answer to any sort of disruption designed to thwart a combo deck, nothing to protect your permanents, etc.

This is where I think things like Wall of Denial and Staff of Domination (while good cards in their own right) are cards that you should consider dropping in favor of cards that can protect your primary combo pieces, and you should up the count of your combo pieces. Infinite tokens seems to be your primary wincon...where infinite mana seems to be extraneous.

Just thinks to consider if you really want to take the deck to a competitive level.

Since you have no removal, you may also want to consider AEther Membrane and Doran, the Siege Tower

Ghostway vs. Boardwipes. Also maybe consider Deadeye Navigator for some fancy combos.

Really cool deck man, +1!

instead of Rootborn Defenses put in Boros Charm

Why only 2OFs for each of your primary combo pieces? Modern is a Turn 4 format and this seems unrealistically slow. Additionally outside of Boros Charm what is protecting you combo from format staples like Path to Exile or Oblivion Ring ?

I would drop Idyllic Tutor entirely in favor of giving yourself 4OFs of each of your primary combo enablers. Drop two of your Overgrown Battlement or Sylvan Caryatid for Drift of Phantasms so they can either be defenders or tutors for your combo pieces.

Sure. Modern being a "Turn 4" format generally means that barring interference from your opponent, most "competitive" decks should be able to consistently "go off" (do whatever it is they are supposed to do to win) by Turn 4. So generally you want to be at least 50% of the time going off by Turn 4.

I hear what you're saying about Drift...yes it is harder to cast than Idyllic but it is also more versatile, not only as a tutor, but also as being both a Defender (useful in your infinite mana combo with Staff) as well as a more effective tutor. (It can get you Staff of Domination as well as all of your enchantment cards except for Splinter Twin.)

Having less of your combo cards does not make you any less vulnerable to Pithing Needle or Surgical Extraction etc. but it DOES make you much less consistently able to get your combo off. Additionally you will need at least something to deal with those kind of threats to your combo. (Either counter spells or some permanent removal of your own.)

Personally, if this is just for your own entertainment with your friends and kitchen table stuff, than fine. Its a deck for fun and enjoy it especially if you have fun playing it and its working for you in your playgroup. But if you want the deck to be competitive within the format for FNM or something like that, then I think it would be helpful to commit to one combo and stick with it. Supplement with cards that will protect that combo from popular disruption methods and have a couple of ways you can win quickly even without the combo going off.

Hope this helps!
