HollowVines: The Opportunity Cost of Explosiveness vs. Consistency

Many of you remember the SCG Deck Tech just after Hour of Devastation's release of Hollow One that skyrocketed Gruul Vengevine to popularity. I had always thought of Vengevine as a fun card, but unfortunately had forgotten about it. That is, until I saw how well it worked with Hollow One in that deck.
Thankfully, I already had my playset of Vengevines, so I could dive into brewing without dropping 120 bucks on these newly spiked cards.
For those of you that don’t know Vengevine, the idea is to get Vines in the yard, cast cheap/free creatures and get back your Vines. You can build a massive board very quickly and just overrun your opponent. What we'll look at today is how going all in on the Hollow One/Vengevine
We'll only discuss mainboards. Sideboards were general hate for all the meta decks. Roll your own mana base.
Iteration 1 – Mono-Red Hollow Vine Aggro/Burn
4 Vengevine
4 Hollow One
4 Lava Spike
4 Faithless Looting
4 Cathartic Reunion
4 Street Wraith
2 Eidolon of the Great Revel
4 Goblin Guide
4 Insolent Neonate
4 Lightning Bolt
4 Blood Moon
18 Lands
Overall Record of 7-3
The plan of this deck was simply to burn and hit the discard into free Hollow One
Running this deck as my first iteration of the HollowVines combo, I discovered that it's incredibly important to time your discards and cycles properly. It feels very bad to go digging with a couple loots only to discard some lands and cast a Goblin Guide
Iteration 2 – Rakdos Deathly Hollow Vine
4 Street Wraith
2 Thoughtseize
4 Death’s Shadow
4 Hollow One
4 Vengevine
4 Faithless Looting
4 Insolent Neonate
2 Collective Brutality
4 Vexing Devil
3 Claim // Fame
4 Lightning Bolt
2 Inquisition of Kozilek
19 Lands
Overall Record of 6-4
This deck was my next stop because it had another piece I had already wanted to try, Vexing Devil
However, Claim makes them make that decision over and over again. You can see that going in black allowed for some hand interaction to better handle some matchups. It wasn't enough.
I found this version to have more options at times, and therefore a bit more consistency, but I think I took it in too many directions. Of course, it led to my first ever Thoughtseize
Iteration 3 – Izzet Hollow Vine
4 Vengevine
4 Hollow One
4 Vapor Snag
4 Street Wraith
4 Insolent Neonate
4 Lightning Bolt
4 Champion of Wits
4 Izzet Charm
4 Faithless Looting
4 Magus of the Bazaar
1 Desolate Lighthouse
19 (Other) Lands
Overall Record of 4-6
Champion of Wits
I will say that the look on your opponent's face when they put you on Storm and you drop a Magus of the Bazaar
Iteration 4 – Mono Red All-In Vines
4 Vengevine
4 Hollow One
4 Simian Spirit Guide
4 Faithless Looting
4 Cathartic Reunion
4 Street Wraith
2 Eidolon of the Great Revel
2 Desert Cerodon
4 Flameblade Adept
4 Insolent Neonate
4 Lightning Bolt
2 Blood Moon
18 Lands
Overall Record of 8-2
This list produced the God-Hand. It simply dumps everything into the combo. If you aren’t going off by turn two, then you're probably losing. The important part though, is beating your opponent into submission before they even get to play Magic.
I know mathematically there could be a better hand, but my God-Hand happened in the first game of my second night against Jeskai Tempo. 1 Mountain
I exiled my Spirit Guide to its ability to cast my first Loot. I drew another Vine and a Mountain
I was able to swing with 20 power on the board before my opponent had played their first land.
Recap
There are some similarities across all these decks that are necessary if you want to get brewing in this same style. Obviously the Vengevine
Neonate allows you stack Loots for later turns and is absolutely invaluable. Faithless Looting
My overall record ended up being 25-15. I don’t know if the decks are as good as that number would let on. It was a small sample size and only played locally. These decks can create some interesting interactions and lines to victory.
Please give one of them a try and see how much power you can drop on the board on turn one! As always, let me know what you guys think, and please give me suggestions on other fun Modern brews!
