Hi, that is a nice deck you are running. I have a Kiki-jiki deck myself too. But as you said it, mine is more competitive 1v1 deck, with land destruction and and other ETB effects to disrupt my opponent. However I do run some of the combos too, and sometimes I've thought to put and all combo deck like yours. Being said that, I think I know some combo pieces that you may missed.
First, if you are running the Twinflame + Dualcaster Mage combo, another card that does the same thing of twin flame is Heat Shimmer. Although it is strictly worst, since it cost 2R and don't have strive, still is a good option.
Second, the goblins. I get that you don't run to many in the deck, but missing the Lightning crafter combo is a shame in my opinion. Specially if you can tutor the pieces either with goblin matron or goblin recruiter. However, you can run a similar combo with another creature with Champion, Changeling Berserker. With him on the battlefield, and any sac outlet, you can copy it with kiki, the copy exiles Kiki with the champion ability, you sac the copy, Kiki enters and you doit all over again, giving you infinite mana or damage depending on the sac outlet. And talking about sac outlets, another good one is Blasting station, since is better for going infinite damage.
Another goblin to combo off, if you decide to include Splinter twin, is goblin sharpshooter. The sharpshooter with the splinter twin plus a sac outlet goes infinite on damage, since you put a token with the splinter, do one damage with the token, sac it, and you uncap the sharpshooter to put a token again.
Finally, another combo that I'm trying out right now is Worldgorger Dragon + Kiki. The combo may be confusing, but it goes like this: with Kiki on the battlefield, you cast the dragon. In response to the dragon ability you copy it with kiki, the copy enters exiling everything (including the original dragon), then the ability of the original dragon resolves, exiling the copy of the dragon, and everything returns to the battlefield (including the original dragon). When the dragon enters again yo do it all over again in response to its ability. By this, you can go infinite with any ETB creature that you have on the battlefield or triskelion.
Hi, first off, I think your post is great, I have a Kiki-jiki deck and Im always looking for new decks posted to come with new ideas for my deck. I agree with all of the things you say about Kiki-jiki, about being a great way to start in commander with a kind of a budget, but still competitive, deck. I did the same transition than you, from a more tribal goblin deck with Krenko, to my almost complete Kiki-jiki deck. The Kiki deck I have is intended for 1v1 (but with wizards banned list), so is centered on disturbing the opponent. I can say that the deck works pretty fine, and can compite at the same level of tier 1 decks, like Derevi, Maelstrom, or Zur. So if you are interested in pretty fun deck, that can sometimes upset many players, I can recommend you a lot of cards:
Mana base: I run 36 lands too, and while its a bit low, I run more mana rocks than you, specially in the two mana slot (iron myr, ruby medallion, Mind Stone, Coldsteel Heart) and some land fetchers (Wayfarer's Bauble and expedition map, specially to look for ancient tomb). I just to play burnished hart, but I found it was too slow. Pilgrim's Eye is much better, and it goes really well with the ETB effects and kiki jiki. I think that low mana cost artifacts are better for kiki, since I don't really play to many huge creatures, and kiki himself its quite cheap to play.
Land destruction: If you are going for land destruction you need to go all the way. I while many cards in this line are very expensive (goblin sttler, blood moon, magus of the moon) there are many cards that are really easy to get, being Avalanche Riders and ravenous baboons the best cards to with kiki. Goblin ruin blaster is another good one, and even if you don't get the effect by copying its good enough that you can fetch it with goblin matron or the recrutier. There are many 5 drops that destroys land at ETB but I don't use specially like them.
The goblins: Even if you don't want to go tribal with goblins, there are plenty that are still good for copying with Kiki. Goblin war marshall, tutu scraper and Stingscouger are great since all of them have ETB effects. But if you want to add more combos, the are few good goblin that can help. Skirk prospector is great if you have your kiki equipped with Thornbite Staff, since you can go infinite by copying and sacrificing it to get all the mana that you want, or to use with other effects like purphoros (goblin chirurgeon could be good too, and to save any creature if need it). Another essential goblin for combo is Lightning crafter, since if you have Kiki in play (and another goblin to champion with the crafter) and any sac outlet yo can go infinite damage. You do this by copying the crafter with kiki, the copy enters championing Kiki, you use de crafter copy ability to deal 3 damage to the player, the you sacrifice the copy, and kiki enter the batlefield untapped to do the same all over again. Plus, you can tutor all of this goblin, so I would recommend Mogg catcher too as a tutor, since red is the weakest color to tutor cards.
Elementals: there are a few elemental cards that go really well with kiki. Ingot chewer and fault grinder have ETB effects, and spitebellows when leaves the battlefield deals 6 damage to a creature, so are good to copy with kiki to double their effects. Another good thing is that if you have kiki in play, and yo play this cards for their evoke cost, you still can copy them when enter te battlefield with the evoke on the pile. And finally you can also tutor all of them with flamekin harbinger, so you can look for other elementals that are good to copy like tyrant of discord.
Finally there are some other combos that you can go with kiki, involving umbral mantle plus Emrakul's Hatcher or priest of urabrask. Also, dual caster mage can go infinite with twinflame or with heat shimmer. well thats all, but I can recommend a lot of other cards that i have tried with my deck. Let me know if you need more help.
