8/23/2016 If the new creature isn’t on the battlefield as the first ability resolves, use its power when it left the battlefield to determine whether its controller may draw a card. Note that effects that reduced its power before it left the battlefield will apply.
8/23/2016 Selvala’s last ability is a mana ability. It doesn’t use the stack and can’t be responded to. If the greatest power among creatures you control is 0 or less at that time, no mana is added to your pool.
