Veha, The Chosen

When Veha, The Chosen enters the
battlefield, reveal the top ten cards of your
library and exile any number of lands from
them. Make a two copies of each land exiled
this way and put them on to the battlefield
under your control. Shuffle the other revealed
cards into your library and untap all lands on
the battlefield.
All lands you control become 4/4 elemental
creatures with haste and are still lands.
