This one weird trick will let you land ramp without searching your library. <--- (Ashiok hates him!!) (EDH / Commander) [Revisão 11]

Here's how to win:
1: Make Cloudpost into a creature:
Quirion Druid
Obuun, Mul Daya Ancestor
Vastwood Animist

Planar Outburst
Part the Waterveil

2: Make a token copy of your animated Cloudpost:
Cackling Counterpart

Mirrorpool
Progenitor Mimic
Quasiduplicate
Repudiate // Replicate
Rite of Replication
Saheeli's Artistry
Spitting Image
Clone Legion
Zndrsplt's Judgment

Mythos of Illuna
Kiki-Jiki, Mirror Breaker

3: Repeat Step 1 for the token land.

4: Populate!

Ghired, Conclave Exile
Growing Ranks
Rootborn Defenses
Selesnya Eulogist

And then you win the game.

We've got a landfall subtheme, so creating token copies of lands is actually pretty good. It also allows you to continue ramping even if your deck has no more lands in it.

Note that making a token copy of something doesn't copy the effects on it. So once you have a token copy of Cloudpost (or any other land), it won't be a creature, instead it will be safely tucked away with the rest of your lands until you're ready to animate the token and start populating. This makes our combo harder to pull off, but it also makes cards like Progenitor Mimic really good. (Look up "MTG Copiable Values" if you want to know more).

If you don't have a repeatable way to animate lands, the manlands like Faerie Conclave, Blinkmoth Nexus, etc. are able to animate themselves.
