Darth Tyranus, Scheming Sith

First Strike, Haste
When Darth Tyranus enters the battlefield, create two 1/1 Sith Apprentice creature tokens. On your Upkeep, put a +1/+1 counter on each Sith Apprentice you control, then if the total power of Sith Apprentices you control is 10 or more, put a +1/+1 counter on Darth Tyranus as well.
