Step 1: Use Mycosynth Lattice to turn Saheeli Rai (and everything else) into an artifact.

Step 2: Use Saheeli Rai's second ability to make a copy of herself. When it enters, Altar of the Brood triggers, and you sacrifice the original to the Planeswalker uniqueness rule. Then, the Altar's ability resolves, and each opponent mills a card.

Step 3: The token of Saheeli can then create a copy of itself the same way, and you repeat the process until none of your opponents have cards in their libraries.

Liquimetal Coating works the same as Mycosynth Lattice way due to Saheeli's clause "except it's an artifact in addition to its other types."

Hope that helps, alexmoro2002.

Yeah makes seens now thanks for the explination [Primusfan42]. I really need to make this combo. Awesome way to get rid of each opponent and also pretty hard to break. A power house :-)

EternalSoldier: You know that only works if you're above 50 life, right? Since the 'Pay 50 life' is a cost of the activated ability, the cost is paid before the ability is activated, if you're at less than 50 life, you can't activate the ability at all.

TheOtherDemko Yes, but it's not hard to get to 50 life in EDH.

Basalt Monolith + Rings of Brighthearth doesn't work for infinite mana, can't copy a mana ability.

Oops, Basalt Monolith + Rings of Brighthearth

You copy its untap ability

Rikeus we copy the untap ability and tap it a second time with another untap trigger on the stack. We need two colorless mana to start it and then it produces infinite colorless.

Sydri, Galvanic Genius + Aetherflux Reservoir or Caltrops get 51 or more life, give Aetherflux Lifelink and death touch and keep firing, and give deathtouch to caltrops for defense

Consider some cruel non-infinite combo's with Mycosynth Lattice such as with Karn, Silver Golem or Hurkyl's Recall or with Vandalblast

A good addition might be Arcum Dagsson to search out your hefty artifacts.

Staff of Domination has numerous infinite combos.

Metalworker is a great fit though a bit pricey.

I really like Mystic Remora in every edh deck I have that's blue the draw potential for 1 blue mana is just too great.

The classic artifact recursion dude Goblin Welder is a good addition.

Mindslaver is a good lock and goes infinite with many things already in your deck and suggestions mentioned above; though it does feel pretty dirty to play with.

Trash for Treasure and Reanimate are some good graveyard recursion cards you may want to include.

Sydri, Galvanic Genius and Aetherflux Reservoir? Pay to make reservoir a lifelink creature and then it's ability becomes "Pay 50 life: lifelink 50 damage" so you can use it over and over to utterly destroy everyone.
