Another possibly relevant trick:
You have two Oaths, a Forbidden Orchard, and your opponent has 1 spirit token at the end of their turn.
At the beginning of your upkeep, both Oaths go on the stack. You resolve the first, and get a creature. You then have time to tap Orchard again to prevent the second from fizzeling.
On the same line, there is a trick to prevent the opponent from using your oath if they have one creature less than you: you tap orchard during his upkeep, thus preventing the oath from resolving succesfully. And in this way the spirit token he has got is under summoning sickness (which would not be if you had created it during your turn).
