Homage to the Ancients

Reclaiming 2 (If an assimilation counter
was placed this turn, Untap two lands you control)
Exile all Lands you control.
Search your library for 2 basic land cards and put
them into play, then shuffle your library.
At the beginning of each phase, return to play
one land exiled from Homage to the Ancients.
The return of a titan takes time.
