I was very happy downgrading the deck to have less combos, but firstly, it didn't stop me being targeted for being a combo deck, and second, I think I need to keep the deck a little more robust to fight some stronger decks. So the combos are back in town baby!
Kiki-Jiki + Zealous Conscripts.
Use Kiki-Jiki to copy Conscripts. The copy's ETB ability will untap Kiki-Jiki, allowing you to repeat. Result is as much Conscripts tokens with haste you want, attack and win.
Tip: The last Conscript could steal a permanent of someone, like a Propaganda.
Kiki-Jiki + Combat Celebrant.
Use Kiki-Jiki to copy Celebrant and enter combat. Attack with the token, exerting it. The Exert ability will untap Kiki-Jiki and give you an additional combat phase. Repeat until the Celebrant tokens kill all blockers and after that all opponents.
Tip: If someone has an indestructible blocker this combo might not do it. An ETB Damage card or Sac Engine would help.
Kiki-Jiki + Lightning Crafter + A Sac Engine.
With Kiki-Jiki in play, cast Crafter, and announce Kiki-Jiki as the one to be Championed. Hold priority and use Kiki-Jiki to copy the Crafter. As the Crafter token enters, announce Kiki-Jiki as the one to be Championed and let it resolve, exiling Kiki-Jiki. Sacrifice the Crafter Token to a Sac Engine for effect (Altar of Dementia to mill or Goblin Bombardment to deal damage). The Champion ability will bring Kiki-Jiki back, untapped, to repeat as you wish.
Kiki-Jiki + Lightning Crafter + ETB/LTB Damage Enchantment.
With Kiki-Jiki in play, cast Crafter, and announce Kiki-Jiki as the one to be Championed. Hold priority and use Kiki-Jiki to copy the Crafter. As the Crafter token enters, announce Kiki-Jiki as the one to be Championed and let it resolve, exiling Kiki-Jiki. ETB Damage (Impact Tremors or Purphoros, God of the Forge, Outpost Siege on Dragons works also) will trigger, dealing damage to your opponents. Tap the Crafter Token (wich has haste) to deal 3 damage to itself, killing itself. The Champion ability will bring Kiki-Jiki back, untapped, to repeat as you wish.
Kiki-Jiki Equipped with Helm of the Host + A Sac Engine or ETB/LTB Damage Enchantment.
Enter combat, Helm will create a nonlegendary Kiki-Jiki token, wich can copy itself, and the copy can copy itself. Create as many tokens as you wish (all but the last one will be tapped). A sac engine than could be used to finish the game, or the ETB damage cards will trigger along the activations.
Kiki-Jiki Equipped with Thornbite Staff + A Sac Engine + ETB Creature
Copy the ETB creature with Kiki-Jiki, triggering its ETB. Sacrifice it to the Sac Engine. The Staff will untap Kiki-Jiki, enabling you to repeat the combo.
Tip: If the ETB creature deals damage (Fanatic of Mogis), you win from there. If the ETB creature creates tokens (Beetleback Chief), you sacrifice one of these tokens, to end up with copies from the ETB creature with haste for you to attack with.
Kiki-Jiki Equipped with Thornbite Staff + Flametongue Kavu + ETB/LTB Damage Enchantment.
Copy Kavu with Kiki-Jiki. The copy entering will trigger the ETB Damage card (Impact Tremors or Purphoros, God of the Forge, Outpost Siege on Dragons works also). Use the damage from the Kavu token to make it kill itself, wich will make the staff untap Kiki-Jiki. Repeat untill everyone else is dead.
Kiki-Jiki Equipped with Thornbite Staff + Emrakul's Hatcher.
Copy Hatcher with Kiki-Jiki. The copy comes with its own Eldrazi Spawns. Sacrifice a Spawn to its own ability, wich will make the staff untap Kiki-Jiki. Repeat as you'd like, ending with as many Emrakul's Hatcher tokens with haste you'd wish, attack for the win.
Tip: You'll also end up with infinite colorless mana, but I don't have any use for it in my deck, if you'd like you could add a Fireball or similar to yours.
Reflection of Kiki-Jiki
Equipped with Thornbite Staff + Emrakul's Hatcher
Similar to above, but in this case, you'll use the mana from the Eldrazi Spawm to pay for Kiki-Jiki-Jr activation. Result is the same.
Reflection of Kiki-Jiki
Equipped with Thornbite Staff + Ashnod's Altar + ETB creature
Pay a mana to activate Kiki-Jiki-Jr and copy the ETB Creature (example: Fanatic of Mogis) and let it do its thing. Sacrifice the token to Ashnod's Altar, Staff will untap Kiki-Jiki-Jr, use the mana from Altar to activate Kiki-Jiki-Jr again. Repeat as you wish.
Krenko, Mob Boss Equipped with Thornbite Staff + Altar of Dementia or Goblin Bombardment.
Tap Krenko to create at least one Goblin token. Sacrifice the token to Altar of Dementia for mill ou Goblin Bombardment for damage. The staff will see a creature dying and will untap Krenko. Repeat until everyone is decked or dead.
Goblin Welder Equipped with Thornbite Staff + Nontoken Artifact Creature on the battlefield + Artifact Creature Card on my graveyard.
At least one of these artifact creatures must have an abusable ETB (like Myr Battlesphere). Or add in an ETB damage card.
Activate Welder, targeting the Artifact Creature and the Artifact Creature Card on the graveyard. As the ability resolves, sacrifice the Artifact Creature on the battlefield and reanimate the one in the graveyard. The staff will untap the Welder, allowing you to repeat as many times you want. Win from there, but this one might not win on the spot.
Dualcaster Mage + Twinflame + Any other Creature under your control.
Cast Twinflame, targeting any creature you control (does not matter), hold priority and cast Dualcaster Mage, targeting the Twinflame on the stack with its ETB ability. This will copy Twinflame. Target Dualcaster Mage with the copy. With the token's ETB ability, target the original Twinflame, and repeat. You'll end up with as many Dualcasters with haste as you'd wish, attack and win.
