- You can use "Xyz Energy" first against any of your opponent's monsters that wouldn't be hard to Summon again and wouldn't be worth the 300 damage.
- Use "Degenerate Circuit" to banish the monsters instead of returning them. Note that this will affect you as well, and that no damage would be inflicted.
- Use "Spring of Rebirth" to gain Life Points from returned monsters, more than recovering any Life Points you would have lost.
