Increasing Savagery and Sins of the Past cast from graveyard no flashback rulings

[lucky]

if I cast increasing savagery from graveyard using sins of the past instead of the flashback, how many +1/+1 counters do i put?

Ten. Increasing Savagery and its pals don't care about how you cast it from the graveyard, only that it was cast from the graveyard at all.
