614.15. Some substitute results should not steady results. Relatively, they’re an impact of a resolving spell or capability that change half or all of that spell or capability’s personal impact(s). Such results are known as self-replacement results. The textual content making a self-replacement impact is often a part of the flexibility whose impact is being changed, however the textual content could be a separate capability, notably when preceded by a capability phrase. When making use of substitute results to an occasion, self-replacement results are utilized earlier than different substitute results.
Alternative results, together with self-replacement results, are utilized as the unique occasion is about to occur. (On this case, the unique occasion is the seek for as much as two fundamental land playing cards.)
614.1. Some steady results are substitute results. Like prevention results (see rule 615), substitute results apply constantly as occasions occur—they aren’t locked in forward of time. Such results look ahead to a specific occasion that might occur and utterly or partially change that occasion with a special occasion. They act like “shields” round no matter they’re affecting.

The setting of Dungrove Elder’s energy and toughness is a steady impact generated by a static capability. Such results are all the time up to date.
611.3. A steady impact could also be generated by the static capability of an object.
611.3a A steady impact generated by a static capability isn’t “locked in”; it applies at any given second to no matter its textual content signifies.
Due to this fact, Dungrove Elder’s energy is 3 on the time the search is about to occur, and thus the self-replacement impact just isn’t utilized and you’ll seek for solely as much as two fundamental land playing cards.
