bottomless trap hole Vs whirlwind

*veramente SUBZERO ha detto cio che credeva, PRIMA che tu mi dicessi la spiegazione.

almeno questa è giusta allora.

si l'effetto della Black Whirlwinds si attiva quando un mostro alanera resta sul terreno. quindi se evocando un alanera e viene negata l'evocazione, o nel caso in cui viene coperto o rimosso dal terreno, l'effetto della Black Whirlwinds sfuma.

Non parte poiche' il mostro deve essere sul terreno quando whirlwind risolve.

Ecco il ruling ufficiale:
The effect of “Black Whirlwind” starts a Chain. If an effect is chained, so that the Summoned “Blackwing” monster is no
longer face-up on the field when the effect of “Black Whirlwind” resolves, you cannot add a monster to your hand.
“Black Whirlwind” looks at the ATK of your newly-Summoned monster as it is on the field. If a Field Spell Card is
increasing the monster’s ATK, you can search your Deck for a “Blackwing” monster that has less ATK than the increased
ATK value.
If you control multiple “Black Whirlwinds,” you can activate all of their effects. They form a single Chain, and you add 1
“Blackwing” to your hand as each one resolves.
If control of the Summoned “Blackwing” monster shifts during or before resolution of “Black Whirlwind,” you can still add a
card to your hand because you can still see the ATK.
