Furnace-Blessed Conqueror

Rulings
Although the token enters the battlefield attacking, it was never declared as an attacking creature (for the purposes of abilities that trigger whenever a creature attacks, such as its own ability, for example).

The token will enter the battlefield and then have counters put on it. In most cases, the game will see a 3/3 creature entering the battlefield for the purposes of any abilities that may trigger.
(wotc • 2023-04-14)
The token doesn’t copy whether Furnace-Blessed Conqueror is tapped or untapped (although the effect itself causes it to enter tapped), whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.
