No Safe Haven

No Safe Haven
Continuous Spell Card
When a monster destroys a Defense Position monster, inflict the difference as Battle Damage to the owner of the destroyed card. When either player activates a Trap Card, the controller of the Trap Card must toss a coin and call it. If they call it right, they gain 500 Life Points. If they call it wrong, the Trap Card's effect is negated.

maybe better as a field spell, it affects both players.
And maybe it's better to say:
When a trap card is activated, the owner of that card tosses a coin and call it.
instead of:
When either player activates a Trap Card, the controller of the Trap Card must toss a coin and call it.
