Fiendish Duo Discussion

DeinoStinkus on Greedy Golos: Treasure Token Tribal

What about Korvold, Fae-Cursed King? I've been thinking about making a Commander focused around him and Treasures. And on a lesser note, Mayhem Devil. Maybe Fiendish Duo to double your damage.

Fiendish Duo is a one sided furnace and you might want to check out the enchantment Repercussion to punish blocking and make burn spells hurt more.

Also, don’t overlook the power of Goblin Sharpshooter. With Torbran, Thane of Red Fell on the field, he is great at killing anything with 3 or less toughness which is great against token decks.

I am a fellow torbran player and these cards are some of my better pieces.

Your deck seems a lot more solid now! You've got good ways to generate advantage and to ramp, now we've got to work on upgrading your removal and getting the synergy in your deck down better.

You've got a copy of Lightning Bolt in your deck, and while I do think the card is underrated, there are better options that should go in a deck before it. Lightning Bolt is a nice one mana, and can kill a lot of common creatures, but also misses the mark on a lot of other common, important creatures. White is the premium color for removal, so you have a lot of options. You have some of the most efficient removal spells in the game with Path to Exile and Swords to Plowshares. You've got enchantment form removal to hits any nonland with stuff like Banishing Light, Oblivion Ring, and Grasp of Fate. You have Creatures that do the same for creatures like Banisher Priest and Fiend Hunter. You have the great new Generous Gift, and you've got plenty of ways to hit artifacts and enchantments like Return to Dust, Heliod's Intervention, Crush Contraband, etc. Then of course, white also has plenty of board wipes, pick the ones you like.

I recommend adjusting your removal count based on play experience. At the end of each game, ask yourself if you felt your deck lacking removal or not. If you did feel lacking, add more in. If you felt you had too much, take some out. Now of course you don't have to remove every threat in the game, the other players will remove each other's things too, but in those key moments it's good to be able to wipe the board or to shoot down that key piece that's gonna swing the game in that person's favor or save your life.

The other thing I noticed in your deck is the tribal synergies. From what I understood, you said you wanted double tribal, and I'm guessing those two tribes are soldiers and angels, or soldiers and humans. Either way, the tribal synergies seem to be a bit lacking. There don't seem to be enough creatures of each tribe to really benefit from the payoff cards, so you might want to look into adjusting the number of tribal cards and payoffs, or ditching the tribal aspect.

Finally, if you've been liking Angrath's Marauders and Gisela, Blade of Goldnight, you might also like Fiendish Duo. Just an idea if you've been liking the big scary creatures that double damage.

Really though, I wanna hear how the deck has been running and how you've liked it. Boros is a lot of fun to play if you like aggression, so I want to hear if you've been enjoying it. Above all card suggestions, having fun with the deck is what is most important.

Hello WarpedZerghead and thanks for your suggestion :)

I feel like I have enough redundancy for this kind of effect with Dictate of the Twin Gods, Gratuitous Violence, Quest for Pure Flame, Overblaze, Fiendish Duo and Desperate Gambit.

In addition, Furnace of Rath is nice but I find upsides to each other damage doubler I actually run.

But I didn't say tutors, I was talking about how design has been exploring parallel effects & political cards & doing it in a way that feels color specific. has been making everyone play with parallel card draw for pain, also political bomb-plays Allure of the Unknown, Captive Audience. hsas a political bargaining card that happens to be a tutor. has been using balance-type effects for awhile now, hopefully they continue to explore. has Fiendish Duo.

iced_gg on Marisi, Control Combat

king-saproling Agreed. Marisi brings some fresh dynamics to the board state. When I started playing with my current playgroup I noticed how often they would go infinite and outright win the game with various combos (something I wasn't very used to in the past). Tutoring for specific win conditions didn't seem nearly as fun or dynamic to me but, I still wanted to be viable within the pod. Marisi has allowed that, literally forcing every single player into awkward interactions. It's been a lot of fun watching high power level combo decks squirm and try to work around the disrupting mechanics. Also, thanks for the suggestions, a few of the cards I've looked at before and are possibly still considering are, Nacatl War-Pride, Keeper of the Fables and Herald of the Host. One with Nature and Fiendish Duo I'm not super familiar with but I like quite a bit, thanks for that.
