Welcome back to Brew City. Ravnica Allegiance is out and there are some exciting cards to brew around. An overlooked card is Incubation Druid. With a +1/+1 counter on him, he can add 3 mana to your pool. This is a very powerful ability in Modern and in the below shell, it can do some crazy things.
4x Botanical Sanctum
4x Breeding Pool
4x Llanowar Reborn
4x Misty Rainforest
4x Birds of Paradise
1x Eternal Witness
4x Incubation Druid
4x Noble Hierarch
1x Simic Guildmage
4x Simic Initiate
4x Vigean Graftmage
1x Walking Ballista
1x Zameck Guildmage
4x Chord of Calling
2x Collected Company
2x Gifts Ungiven
1x Postmortem Lunge
4x Serum Visions
3x Sleight of Hand
Incubation Druid + Vigean Graftmage = Infinite Mana
As long as Incubation Druid has a +1/+1 counter on it, it can tap for 3 mana, of which 2 can be paid to untap itself via Vigean Graftmage, leaving you with a surplus of 1 mana of either blue or green.
You can place a +1/+1 counter on Incubation Druid with Graft from Llanowar Reborn, Simic Initiate and Vigean Graftmage.
We can combo off as early as turn 3:
Turn 1: Forest + Simic Intitiate OR Llanowar Reborn
Turn 2: Land + Incubation Druid (grafting counter from Simic Initiate OR Llanowar Reborn)
Turn 3: Vigean Graftmage (tapping Druid to cast, then using the 2 remaining mana from your lands to untap the Druid)
With infinite mana, there are 2 main ways to win. 1st is using Zameck Guildmage’s second ability to draw cards. You can remove counters from Incubation Druid to draw. Once he has no more counters, he can replenish the counters via Adapt. You can draw your entire library until you find a Walking Ballista and cast it with infinite counters for the win.
Another path to victory is through Simic Guildmage. His first ability allows us to move +1/+1 counters onto other creatures. If we have infinite mana, and can generate infinite +1/+1 counters on Incubation Druid, we can move them to other creatures such as a huge flying Birds of Paradise and attack for the win.
The tutor and filter:
The advantage of playing Blue is that we have access to a lot of cantrips to filter through our deck. We run Serum Visions and Sleight of Hand so we can quickly get to our combo pieces.
For tutors, we have the classic Chord of Calling and Collected Company. Since we are playing Blue, we have access to Gifts Ungiven to directly tutor missing combo pieces. With Eternal Witness and Postmortem Lunge, we can always make sure we get back the cards that were chosen to go to the graveyard.
There are definitely room for flex spots in the deck. For example, counterspells like Remand and Cryptic Command to protect our combo.
There is no sideboard list right now but I can see a couple of counterspells such as Spell Pierce or Heroic Intervention to protect the combo. Against aggro, we may even consider the new Hydroid Krasis to gain some life and draw our combo pieces.
All in all, the core of the deck is as potent as Counters Company (Vizier of Remedies and Devoted Druid combo) and I can’t wait to try it out in the post-KCI era.
