Presence of Gond Combo

Resolving a presence of Gond on a midnight guard to make infinite elf tokens is awesome and this is what this deck can do. It has the redundancy and the tools to get the combo going, wich, btw, is not even the only way to victory (have you ever seen a mono blue delver going?!).

Golem Damage

Battered Golem + Retraction Helix Allows to bounce 1 drop artifacts like Sunbeam Spellbomb, Aether Spellbomb, or Chromatic Sphere infinitely as long as Etherium Sculptor is on the board. This can pump up Golem Foundry for infinite 3/3 golem tokens on turn four, or Glassdust Hulk for infinite damage on turn five.

T1: Seat of the Synod, Chromatic Sphere
T2: Ancient Den, Etherium Sculptor, Chromatic Sphere
T3: Ancient Den, Battered Golem
T4: Seat of the Synod, Golem Foundry, Retraction Helix on Battered Golem to bounce Chromatic Sphere infinite times for infinite charge counters and infinite Golems tokens.

Plenty of other ways to win without the combo Etherium Sculptor + Frantic Salvage allows for recycling tons of spellbombs and spheres for very little mana. Then there's just plain old affinity, bringing out Myr Enforcer as quick as turn two.

The Blue Combo

The Combo is turn 1 Spidersilk Net and island turn 2 Elusive Spellfist and island turn 3 Zephyr Scribe and Island turn 4 Retraction helix onto zephyr scribe bouncing back spidersilk net then replay it growing elusive spellfist and do that infinitely and because elusive spellfish becomes unblockable you can hit for a high amount.

UW Reality Acid

Here's a deck that uses Spreading Seas to destroy their mana base and Dream Stalker Kor Skyfisher and Momentary Blink to bounce things like Reality Acid and Serrated Arrows for creature kill or just use Journey to Nowhere.

Also includes Mulldrifter Sea Gate Oracle Lone Missionary Faith's Fetters that you can bounce for card advantage and life gain.

Turbo-Fog Mill

Turbo Fog Mill uses Jace's Erasure with cheap card draw like Brainstorm Words of Wisdom See Beyond and Fog effects plus lifegain to stall out the opponent for long enough to mill them.
