Steven, Uwu of the World

Eminence—At the beginning of your end step,
if you control three or less lands and you have
not played a land this turn, and
Steven, Uwu of the World is in the command
zone or on the battlefield, search your library
for a basic land card and put it on the battlefield tapped, then shuffle.
Whenever another Cat you control attacks, you may pay {1}{g}{w}. If you do, it gains trample and get +X/+X until end of turn, where X is its power.
