Rulings
Kenrith's last ability can target a creature card in any player's graveyard. Its owner will control the creature, and it will remain on the battlefield even if you leave the game (if you don't own it).

Kenrith's first ability affects only creatures on the battlefield at the time it resolves. Creatures that enter the battlefield later in the turn won't gain trample or haste.
