If you would begin a combat phase, you may skip that phase and begin an additional upkeep step instead.

Whenever a player casts a spell from their hand, they reveal the top card of their library. If it's a nonland card with a mana value less than that spell's, they may cast it without paying its mana cost. Otherwise, they put it on the bottom of their library.
