His power is: you may take an extra "clear an obstacle" action (store card here). I have some questions:
1. Can he use this power even when the team hasn't taken 4 actions, thus allowing the team to draw extra cards even after effectively taking 4 actions?
2. Can he use this power to clear a multi-symbol obstacle, or when using two cards as a wild? I ask because it says "store card", not "store card(s)".
3. Can other players contribute a card to this extra action? Or must Mikey perform this action alone?
1. Yes. This is one of the main reasons to use the power.
2. Yes and yes
3. No. He does this clear alone
