Forests that enter the battlefield while Life and Limb is on the battlefield will enter the battlefield as creatures. They’ll have summoning sickness.
Saprolings that are on the battlefield while Life and Limb is on the battlefield have the ability “
: Add .” Although they’re Forests, they are not basic lands.
With Life and Limb on the battlefield, Mistform Ultimus will be a legendary 1/1 green land creature that has land type Forest and has all creature types.
Each Forest and Saproling will have the card types creature and land, and the subtypes Forest and Saproling. Each subtype maintains its correlation to the proper type: Forest is not a creature type and Saproling is not a land type.
When Life and Limb leaves the battlefield, the effect ends and the permanents go back to what they were (unless another effect grants these card types and/or subtypes to the affected permanents).
