You can only activate 1 trigger effect in your hand per chain, so you cannot activate this card's ① effect in the same chain as EG "Gorz the Emissary of Darkness".
This card's ATK is treated as 0 while in your hand/face-down, so it can be destroyed by "Deck Devastation Virus" in those locations.
If this card's atk "becomes" some other value (eg by "Blackwing – Gale the Whirlwind" or "Shrink", its ATK "freezez"; it won't change if the number of cards in your hand changes.
[FORUM] "Solemn Warning" can be activated to negate the Special Summon of "Tragoedia" during the Damage Step.
