Q:If I use this card's [Start of Your Main Phase] effect to place a card under a Tamer with cards under it, in what order do I place the card?

A:The card is placed on the bottom of the cards under the Tamer.

Q:I have 2 copies of this card in the battle area. The [Your Turn] effects on both copies triggered, and I used the [Your Turn] effect on the 1st copy of this card to attack. Can I then use the [Your Turn] effect on the 2nd copy of this card to attack?

A:No, an attack using the 2nd effect isn't possible. A new attack declaration can't be made during an attack. In this case, the [Your Turn] effects on both copies trigger, and you use the [Your Turn] effect on the 1st copy of this card to attack. The 2nd [Your Turn] effect can be activated before the counter timing, but because you can't declare another attack during an attack, you won't be able to attack using the 2nd effect, even if you activate it.
