Non-serialized versions of Traveling Chocobo are mechanically identical to serialized variants
Its a new enchantment that lets you duplicate creature and artifacts you control whenever you target them as the only target of a spell
If the creature copied by the token had any "when [this permanent] enters" abilities, the token also has those abilities, and they'll trigger when it's created
However, the effect counts only opponents (and not planeswalkers or battles) that you attacked with a creature when determining the bonus
That said, Terra, Herald of Hope isn't actually optimized here, as the deck still focuses on larger reanimation targets overall
And, at risk of going on an entirely too long tangent, Ive just finished Clair Obscur: Expedition 33
