Growing Rites of Itlimoc

Oracle Text
When Growing Rites of Itlimoc enters the battlefield, look at the top four cards of your library. You may reveal a creature card from among them and put it into your hand. Put the rest on the bottom of your library in any order.
At the beginning of your end step, if you control four or more creatures, transform Growing Rites of Itlimoc.
Actually, this card could single-handedly push a Servo/Thopter deck into viability in Standard, assuming it also has something to ramp into (Walking Ballista?)
used to be a fun game
You mean I can use Natural Affinity with this?
