Isn't the lizard used with it?

It seems like it is used: once, a bunch of lizards came out against me, clearly more than the number of breeders that were played.

Haven's Etheria (it's Echelon's tutor!)

More likely Aegis. And Taurus. And Echelon is no longer needed when Avatar is available. It destroys amulets immediately, not at the end of the turn, leaving the hatched creatures vulnerable to all enemy removal spells.

And Chimera, Chimera! I want to build a viable deck with it.

According to the link to the tier list that Tox posted, there is a shift deck with old Chimeras and one new one.
