Yoda, Master Jedi

At the beginning of your upkeep, reveal the top
card of your library and put it into your hand. If
the revealed card is a creature card, put two blue
1/1 Padawan creature tokens onto the battlefield.
If the revealed card is a land card, add two mana
of any color at the beginning of your first main
phase. If the revealed card is a noncreature,
nonland card, you may cast it for free this turn.
