Life and Limb

yes they can be boosted... gives forests the additional subtype creature: saproling and the saproling the sub type land: forest so they can all be boosted... also since your creatures are now lands use prismatic omen to make them all tap for any color mana

Does anyone know if the saprolings can still be boosted, or do they have to be 1/1s? Like if I had Coat of Arms out?

Permanents with a basic land type can tap for a mana of the color that a land of that land type would usually produce - Life and Limb enables all of your Saprolings to tap for a green mana, but as all of your Forests (and Saprolings) are creatures, each of them have summoning sickness, which means that you are no longer able to tap a Forest for mana the turn you play it (at least not as long as Life and Limb is on the battlefield). This also means that Prismatic Omen allows all of your lands to tap for a mana of any color, because they gain each basic land type.

Life and Limb is a good card, but the problem is that your lands become extremely vulnerable to a single Pyroclasm or Wrath of God/Day of Judgement.

Does this mean you can now actually tap your saproling creatures for a green mana? Or do they just count as forests for other effects that say "all forests" or "all lands"?
