Nantuko Husk, Blocking, Sacrifice

[Forhigher]

I head that the sacrifice ability wasnt allowed to take place after the declare blockers step. Ex: I atk with Carrion Feeder, blocked by Thorn Elemental . Can i sacrifice 3 creatures to give Carrion Feeder +6 +6, after Thorn Elemental is assigned as a blocker?

[Keyeto]

Yes you can. After the blockers are declared, you are passed priority and are able to sac the creatures for your feeder.

Sry, the card i ment was  {Nantuko Husk} . But the point was a buddy told me the rules had changed i was just checking.

What about when I block I have a card that says  forest sacrifice search you library for a land after I block can I still do its ability

[Double-O-Scotch]

Yes. Activated abilities of creatures work at instant speed ( as long as they don't have summoning sickness) and can be activated after it blocks.
