Trample
When Trench Gorger enters the battlefield, you may search your library for any number of land cards, exile them, then shuffle your library. If you do, Trench Gorger's power and toughness each become equal to the number of cards exiled this way.

After the ability resolves, Trench Gorger’s power and toughness won’t change if one of the exiled cards leaves exile.

If Trench Gorger leaves the battlefield before its triggered ability resolves, you may still search your library.

If you choose not to search, Trench Gorger will simply be 6/6.

While Trench Gorger’s ability is on the stack, it’s on the battlefield as a 6/6.
