Hi! My name is Joseba García aka Elfkid in Magic Online (MTGO) and this is going to be my first article for Hareruya I hope you enjoy it and I hope I can continue writing for them.
I’m going to talk about Pioneer’s new hot deck: Thassa’s Inverter!
How the Deck Works
The combo works exiling your library with 《Inverter of Truth》 and then playing a 《Thassa’s Oracle》 to win the game, it’s more or less a two combo pieces deck but it can also win attacking with 《Inverter of Truth》, since it’s a 6/6 body that a lot of decks can’t beat.
Dimir Version by kanister
First of all I’m going to talk about the regular version and probably the most known one, my teammate kanister (Piotr Glogowski) has been streaming it so if you know him you all probably know what I’m talking about:
4 《Watery Grave》
2 《Fetid Pools》
4 《Fabled Passage》
4 《Drowned Catacomb》
2 《Temple of Deceit》
1 《Choked Estuary》
1 《Castle Vantress》
-Land (25)- 3 《Thassa’s Oracle》
3 《Brazen Borrower》
4 《Inverter of Truth》
1 《The Scarab God》
2 《Drown in the Loch》
2 《Thought Erasure》
4 《Dig Through Time》
2 《Jace, Wielder of Mysteries》
This is a Dimir Control deck with the combo, this means the deck can work as a control deck and win games with a 《The Scarab God》 or with 《Inverter of Truth》 protected with disruption in the forms of discard spells or counterspells.
The best thing about this combo deck are the cards themselves, 《Thassa’s Oracle》 is a good blocker and it also helps you to dig in to your deck and find the cards you need and as I said before 《Inverter of Truth》 is a good beater and a good blocker.
Sultai Inverter by Elfkid and Fradelrock
Now I’m going to talk about the version I built with a friend of mine and we think it might be the best version of the deck; Sultai Inverter.
4 《Breeding Pool》
4 《Overgrown Tomb》
3 《Watery Grave》
2 《Hinterland Harbor》
1 《Drowned Catacomb》
1 《Woodland Cemetery》
3 《Botanical Sanctum》
1 《Blooming Marsh》
2 《Yavimaya Coast》
-Land (22)- 4 《Sylvan Caryatid》
4 《Thassa’s Oracle》
3 《Paradise Druid》
4 《Inverter of Truth》
2 《Hostage Taker》
3 《Fatal Push》
3 《Finale of Devastation》
4 《Eldritch Evolution》
1 《Murderous Cut》
2 《Jace, Wielder of Mysteries》
As you can see, this version is kinda different from the original one, this one is based on abusing 《Eldritch Evolution》 and the Hexproof two mana dorks to search for the combo pieces more consistently, this allows you to also play some silver bullets in the sideboard to fight the hate cards without diluting your deck in the process!
To try to make the deck more consistent we added the card 《Finale of Devastation》, which allows us to find both of the combo pieces and silver bullets like 《Hostage Taker》 main deck and 《Reclamation Sage》 or 《Tireless Tracker》 post board.
Card Choices: Mainboard
Analyzing the deck and the sideboard choices.
These are the cards that makes our deck different from the other versions, having access to a third color and a fast way to build our combo it’s pretty important and this is one of the reasons that make us think this might be one of the best versions of the deck.
The reason to play Green, the cards that enable us to find silver bullets and to have a more fast and a more consistent win, with the help of the Hexproof two drops I mentioned before this allows us to avoid removal spells and win easily. Remember 《Finale of Devastation》 can get creatures from the graveyard so that makes the card super broken!
Disruption and Removal
Even if we’re not a control deck we still need ways to interact with the creatures and the spell based decks in the format. For this purpose we count with the best disruption spell in the format and with one of the best cheap and efficient removals. We also count with the help of 《Murderous Cut》 which works as an additional removal and a way to remove the cards we don’t want to shuffle with 《Inverter of Truth》 back in our library.
I don’t think I need to go deep on this card, it is the best and cheapest cantrip in Pioneer so we need to play it.
This card counts as a Silver Bullet and also as a removal, it’s a pretty interesting card since you can use it in an infinite ways, the best thing is that is a removal that doesn’t go to the graveyard. It’s also good against control decks because we can target our own creatures like 《Thassa’s Oracle》 and we can play around 《Supreme Verdict》 or another sweeper. It gives an extra devotion for 《Thassa’s Oracle》 and it can be searched with 《Eldritch Evolution》 and 《Finale of Devastation》, so it turns our tutor effects into removals too.
Card Choices: Sideboard
About the fifteen cards we’re going to use we prioritized having cards that allowed us to change the deck from a combo deck to a midrange decks, especially mention to the cards 《Pack Rat》 and 《Tireless Tracker》. Both of these cards are pretty good in matchups where we want to side out cards like 《Eldritch Evolution》 to have a more consistent amount of threats.
In sideboard games it’s pretty important to understand we’re not going to work as a focused combo deck like we did in game one, we can grind our opponents out with the help of discard spells plus 《Pack Rat》 like in the old Theros Standard, and the function of cards like 《Thassa’s Oracle》 and 《Inverter of Truth》 in postboard games are to dig in our deck to find the sideboard cards and to help us close the game in the air!
Pros and Cons of Playing Sultai over Dimir
Let’s check how we can cover the most played decks in Pioneer right now with the sideboard guide.
Keep in mind that this deck is relatively new and that I’m trying to not be focused on the combo part in post board games unless I think is really necessary.
Mono Black Aggro
They’re going to side out 《Fatal Push》 most likely so 《Pack Rat》 might be pretty good here. If there’s a game three and they already saw 《Pack Rat》 you can side them out and make them have bad cards in their deck.
Niv to Light
They’re going to try to remove our win conditions in the form of 《Unmoored Ego》 or to try to stop us winning in separated turns with cards like 《Rest in Peace》 so having a midrange plan with counterspells works pretty well.
Mono Green Aggro
This matchup is a race, just try to combo them as soon as possible and use the removal to keep yourself alive until then. 《Reclamation Sage》 blocks and destroys 《Scrapheap Scrounger》, 《Heart of Kiran》 and also helps against 《The Great Henge》, this last one is hard to beat so don’t count it as a real target.
This matchup is close to the Mono Green one but in this one they have burn spells and they’re not focused on the one drops so this might be harder, but the game plan is still the same, just try to combo them fast since they don’t have a good way to interact with us.
This matchup is where our sideboard shines, we’re not focused on the combo part and we use 《Thassa’s Oracle》 and 《Inverter of Truth》 as value cards and as a fast clock one, 《Thassa’s Oracle》 is incredibly good here, since it pushes Planeswalkers and helps us finding the other pieces or disruption. It also works pretty well with 《Tireless Tracker》‘s Clue allowing us to draw the card we want the same turn we play it.
Mono Green Ramp
This matchup is, in theory a good one, but I also like to have ways to interact with cards like 《Thought-Knot Seer》 or the big drops they play in the form of 《Mystical Dispute》. 《Tireless Tracker》 is better than the removal spells and it also gives us card advantage.
Tips and Tricks
I’m going to write a few tips that came in along my games that I think they can be useful for you:
How to Improve the Deck
In my testing I found that the mana base is not perfect, we need to take another look in to it and see how can we add more blue sources, maybe more 《Yavimaya Coast》.
As I’m finishing this article I saw people playing 《Ashiok, Nightmare Weaver》 against the mirror which I think it’s pretty good.
I also think we can add 《Ashiok, Nightmare Muse》 as a sideboard option against the mirror and against hate cards since it can bounce everything.
I hope you all enjoyed this article as I enjoyed writing it. I think this deck is pretty good and I know some friends of mine that are going to play this in Brussels, and thanks a lot to Diego Fradejas who helped me building this deck and the sideboard!
I hope you all can give this a try and let me know how it goes!
