List of Compact Combos

[Papillon]

You need a target to be able to play Pact of Negation. Their Pact can also target whatever your Pact targeted.

So their Pact counters that spell, and your Pact is countered on resolution due to not having a legal target, and you don't have to pay the cost.

look at Magosi, The Watervell. combine it with Clockspinning. Two cards, Five lands in play... Infinite turns.

[JeroenC]

Doesn't work. Clockspinning needs another counter on the permanent to work.

you need to have 6 lands because Magosi requires U to use. Also one of the drawbacks is that it requires you to first skip your turn.

[DownSyndromeKarl]

that combo could work, if you skipped your turn to put a counter on it in the first place. Then used Clockspinning to add a second counter before you remove one to start taking extra turns. Is it combo? Sure. Is it really worth it? No.

[JeroenC]

That combo won't work, as you have to bounce the land to take a turn and by doing that, you lose all counters. RTFC.

[DownSyndromeKarl]

haha, and you couldn't have said that to start?
Its a shitty card that will never see play, so I didn't read it carefully, sue me.

[Infinitium]

Gifts Ungiven -> Vampire Hexmage/Dark Depths/Grim Discovery/Regrowth

1-card 4-mana tutor into a 4-mana win by 20/20 two turns later. Also the only truly dead card in that pile is Dark Depths. Decent.

RTFC was mostly intended for the people who thought it was a combo.

[Offler]

oops. i didnt noticed that it returns to hand :)

Clockspinning can work when there is a counter on it, but while it returns it wont work.

[deadlock]

Thopter Foundry + Sword of the Meek, backed up by something like Academy ruins and maybe Chrome Mox, so that you only need Foundry in play with Sword in the graveyard.
What do you think - how good is this against decks like Zoo?

[Bigface]

Add Carnival of Souls for infinite tokens, or Time Sieve for infinite turns, or both.

Also, Carnival of Souls allows you to combo out really fast.

Seems too slow and too vulnerable to Qasali Pridemage main and Krosan Grip from the side. You'd need to have another plan in case you couldn't get Foundry to stick.

There's also the fact that it costs two mana and isn't a creature, making it rather difficult to tutor for.

EDIT: Enlightened Tutor is just about it. Could be workable in a Counterbalance deck that wins without Tarmogoyf, but there's not much else good in those colors to run after you add Swords and Bob. Esper Charm? Seems workable against control and Counterbalance, but awful elsewhere. Disciple? Maybe, but that pushes you towards traditional Affinity, which has no use for this combo.

Your best bet may be , using Tarmogoyf and Maelstrom Pulse, along with Dark Confidant and Counterbalance. You'd need to diversify your curve, though. Going straight for this combo seems weak since it's not like Painter-Stone where both halves have several cards you can use as tutors (Trinket Mage and Imperial Recruiter).

[Illissius]

Woah. 10 years later and we finally have a use for Carnival of Souls?

[IXEquilibrium]

Null Rod + Mycosynth Lattice is essentially a game ending combo if you have a better board position.

I have a copy of each of these cards in my semi-casual B/U/r Goblin Welder deck. It is very rare that I end up hardcasting the whole combo, although I guess you could if you really felt like it. Generally I'll hardcast Null Rod and Welder in Mycosynth Lattice in the same turn. It's not terribly hard to disrupt (any creature kill or stifle will do it if you are relying on welder). Having Anger in the grave helps a lot though since Welder can activate immediately.

I usually only go for the combo if I'm using the deck in multiplayer (things like Inkwell Leviathan and Platinum Angel tend to be more useful in 1-on-1). A single copy of Darksteel Collossus makes it so I don't get decked if I have have cleared the board prior to playing the combo.

[Barook]

Yeah, hell has frozen over.

A nice little interaction I noticed yesterday:

Kira, Great Glass-Spinner + Ethersworn Canonist

It makes your creatures immune to non-permanent spot removal because they can only play one spell per turn - which is blocked by Kira.

[Phoenix Ignition]

Sort of, but they still could use Firespout, Pyroclasm(okay anything like that, not going to list the rest), Wrath of God, etc.

[OneBigSquirrelGod]

Easy.. You run:
Ashnods Altar
Banefire
Enduring Renewal
Ornithopter

You sac the thopter to the altar, comes back, sac get infinite mana and Banefire them outta the Game

Or you could do the
Ashnods Altar
Fecundity
Saproling Cluster

You discard, make a guy, sac the guy, get 2 mana, draw a card from fecundity, pay one, repeat, sift through your whole deck, and get close to enough mana to Banefire'm outta the game!

[rufus]

Not really a combo, but you'll typically get to swing for the win on the following turn:
Skill Borrower + Congregation At Dawn -> Phyrexian Devourer x2 Jodah's Avenger

Activate the Devourer Abilities, then use The Avenger's Ability to keep the power below 7. (Once before the first Devour resolves, 6 times before the second.) On the following turn, use Jodah's Avenger for Shadow & Double Strike to swing for the win.

[Reverend Damaged]

Not really a combo, but you'll typically get to swing for the win on the following turn:
Skill Borrower + Congregation At Dawn -> Phyrexian Devourer x2 Jodah's Avenger

Activate the Devourer Abilities, then use The Avenger's Ability to keep the power below 7. (Once before the first Devour resolves, 6 times before the second.) On the following turn, use Jodah's Avenger for Shadow & Double Strike to swing for the win.

Wouldn't you just activate the first Devourer, then on the stack, activate the second one's ability, leaving you with just the Avenger on top before she even gets the counters, saving her?
