To make a OTK deck, you must pick a OTK combo, a stalling way and just put them together; they must be compatible though. Think about Horse (OTK combo) + Wings (stalling way) = Pegasus (OTK deck). The horse must be small enough to be able to fly –less than 9 cards- and the wings big enough to make the horse fly. Quanta generation and other personal additions are like the glue and stuff you use to stick the wings into the horse’s back and have a funny result.
Pack 1 and only 1 of the OTK combo cards in order to use the remaining deck space for stall and drawpower.
Having repeated cards makes you draw unwanted extra cards, which you may later need to discard or waste quanta playing them in order to draw more cards.
YAY, the interesting part (or almost)!
I will list most of the ones that are in the forums, which, as you see, are a lot.
After this section there’s the real tutorial of how to build an effective OTK deck.
Rainbow Dragon OTK

4vf 52h 560 58r 5bt 5f2 5id 5la 5op 5rm 5ul 61r
Rainbow Dragons, the most common and representative OTK combo. Pick 5 dragons to reach 50 damage, Sky Blitz to duplicate it, Chimera to make it bypass shields and enjoy.
Buffed Dragons

55q 55q 5fb 5op 5rm 61r 61r
Another Dragon OTK combo. This one requires way less quanta than the one just mentioned and can be powered partially with Novas, but requires 1 more card than the other one. Note that the dragon can be changed and a Momentum can be replaced for a Blessing for more attack.
Mono Dragons

5op 5rm 5rm 5rm 5rm 5rm
5 10-att dragons and Sky Blitz deals 100 damage. This can be done with any 10+ att dragon, I chose Devonians because I like them (and they synergize with :time drawpower). I could have chosen Bone dragons because of Bone Walls or Purple Dragons to stall with Antimatters, as examples. A Chimera in the end is nice to bypass shields.
Fractalled Dragons

5op 5rm 622
This way to generate dragons requires less cards, but you need to get somehow your hand free! Same comment about Chimera as the combo just above.
Parallel Dragons

5op 5rm 61r 61r 61r 61r
The advantage of this build is that, if you balance your quanta right, you should be able to get all that :aether quanta needed quite easy.
Unstable Gas
Hover over cards for details, click for permalink
5om 5om 5om 5om 5om
To draw 5 UGs you can choose the stall you like most, but for PC reasons it's a good practice to have a Silence or Cloak, both castable with a couple of novas. To get the :fire quanta you can use the mark, fire pillars/pendulums or an Immolation!
Blue Nymph

Blue Nymph generates cheap Unstable Gases.
2 Catapults
Hover over cards for details, click for permalink
561 561 595 595 595 5i7 5l9 61r
This combo requires 2 Catapults. Freeze a Photon (or any creature, actually), cast Basilisk Blood 3 times on it, freeze it, copy it and catapult them, reaching more than 100 damage in one turn.
1 Catapult
Hover over cards for details, click for permalink
560 561 595 595 595 5i7 5v0 61r 61r
This combo requires only 1 Catapult, but way more :gravity quanta.
Self-damaging Voodoo Doll
Hover over cards for details, click for permalink
595 5lc 5lc 5lc 5on 5v0 61r 61r
The combo is to play on your Voodoo Doll: Basilisk Blood, 3 Holy Lights, 1 Shockwave and 2 Parallel universes, inflicting 3x34 = 102 shield-bypassing damage. Note that the Voodoo Doll can be played early if your hand gets clogged.
Self-damaging Voodoo Doll 2
Hover over cards for details, click for permalink
5fb 5fb 5fb 5v0 61r 61r 61r
Play the Rage Potions followed by the Parallel Universes on the Voodoo Doll, dealing 120 damage in one turn. Optional momentum to make it haxx shield proof.
Another very similar way to do it is with 2 Rage pots and 4 PUs. It requires more quanta, but it can be easier to get it depending on the quanta production.
Pandemonium Voodoo
Hover over cards for details, click for permalink
4vp 4vp 4vp 4vp 4vp 4vp 5v0
The strategy is to multiply the Voodoo Dolls with Fractal or Mitosis. When you have many dolls, throw 4-5 Pandemoniums in the same turn. They will hurt and copy the dolls enough to kill your opponent!
Ball Lightings

74g 7n9 809 809 809 809 80i
Play 4 BLs, then Fractal, then play the other 6 BLs you just fractalled.

717 717 717 7ta 7ti 809 809 80i
Quite funny, dies against PC and a shield breaks it, but who cares? You kill him with skeletons!
Hover over cards for details, click for permalink
7n9 7nq 7nq 7nq 7nq 809 80i
An upgraded, ostentatious way, but it only requires some :aether and no Chimera!
Fire Bolt
Hover over cards for details, click for permalink
5f4 5f4 5f4 5f4 5f4 5f4
A classic in old times, with Dimensional shields and maybe Sundials you can easily get the 59 :fire quanta you need to reach 102 damage. 69 :fire quanta if you have 5 bolts!
Vulture pseudo OTK
Hover over cards for details, click for permalink
52k 5f8 5oh 622
With Aflatoxin or nightmare Photons you make your opponent have many small creatures (less than 3 HP). Then, you Fractal the Vultures, kill the opponent's creatures with RoF or Thunderstorm and optionally play a Chimera to bypass shields. This combo can deal 200+ damage with a Sky Blitz, being able to be used in Arena and False Gods.
Let's start with this and let the most interesting part for later. This is essential to make a OTK work, so don't overlook it!
You will find cards that haven't been used for OTK stalling yet, but I mention them because there's always room for creativity.

6x Precognitions + 6x Sundials = 12 cards less in your deck + 6 stalling turns. It tends to be almost enough against unupped rushes, and enough against other strategies. Hourglasses work awesome in time-based decks for a controlled and constant drawpower. Even a pair of them can be used as drawpower in a Supernova-based deck.
6x Dim Shields = 18 stalling turns. Tons of PC with some hard hitters is a bitch against them though.
Wings can be more or less mighty than the Dimensional Shields, depending on the opponent's creatures. They block like 60% of the total amount of creatures, so making Wings decks may be worth it.
Shard of Bravery works good if you have sundials or shields to block the opponent's creatures, use them carefully!

Anything that heals you makes you win turns. Hopefully, you may outheal your opponent and end with 100ish HP.

Stopping creatures is an effective way to make time, as 95%ish of the decks rely on attacking creatures. They are to be quite good with shields, but I won’t put another pic just for the shields. I don't remember any quanta denial based OTK in the forums, but they give room for creativity.
