Splintering Deadwood (Blue)

This may trigger twice: once when it attacks and once when/if it hits.

You choose whether or not to destroy an aura at the time the trigger resolves. There’s no priority between choosing to destroy an aura, creating a Ruenchant token.

You may only choose to destroy an aura only if you control an aura.

When you destroy an aura owned by an opponent, it goes to their graveyard, (or ceases to exist if it’s a token).
