Forum:Second Coin Toss

The card "Second Coin Toss" is slightly grammatically confusing.

"As long as this card remains face-up on the field, you can negate the effects of a card requiring a coin toss once per turn and redo the coin toss."

Well, I realize the older cards are unclear on their definition sometimes, but I think this time is my dumb mistake.

Is the card translating: "Negate the effect of a card that requires a 'once per turn' Coin-toss"? or "Once per turn, negate the effects of a card requiring a coin toss"?

My question leads to this situation. A person Summons an Arcana Force monster, flips a coin, establishes its effect, then ends their turn. Could they, on their next turn, activate the effect of Second Coin Toss to negate the effect of the Arcana Force monster, and re-toss to receive the monster's effect?

I apologize if this is far too obvious to receive an answer, but I really think the card should be reworded...
