Q1: If this card digivolves from a Tamer that was played this turn, can it attack in the same turn?
No, it can't. Even if a card digivolves from a card that was placed on the field in the same turn, it can't attack during that turn. It can only attack in the turns after it's played.
Q2: Does the digivolution requirement that this card digivolve from a Tamer mean the Tamer that becomes a digivolution card is treated as if it is a Digimon when digivolving?
No. Digivolve from the Tamer as such, and do not treat it as if it is a digivolving Digimon. "When digivolving" effects and "when a Digimon digivolves" effects don't trigger. Additionally, if a "Digimon can't digivolve" effect has activated, you can still digivolve from a Tamer with this digivolve requirement.
Q3: Do I perform a digivolution bonus draw even if I digivolve from a Tamer?
Yes, you do. A digivolution bonus draw is performed for any kind of digivolution.
Q4: Is a Tamer card placed under a Digimon considered a digivolution card?
Yes, it is. If the Digimon leaves the field, that Tamer is trashed like normal digivolution cards.
Q5: Does a Digimon gain the security effects in the lower text of a Tamer card in its digivolution cards?
No, it does not.
Q6: Does a Digimon gain the inherited effects in the lower text of a Tamer card in its digivolution cards?
Yes, it does.
