If the Dragon that entered the battlefield is copying something else as the triggered ability resolves, the token will be a copy of whatever that creature is a copy of.

Miirym, Sentinel Wyrm keyword rules

Flying Rule 702.9

Flying is an evasion ability.

A creature with flying can’t be blocked except by creatures with flying and/or reach. A creature with flying can block a creature with or without flying. (See rule , “Declare Blockers Step,” and rule , “Reach.”)

Multiple instances of flying on the same creature are redundant.

Ward Rule 702.21

Ward is a triggered ability. Ward [cost] means “Whenever this permanent becomes the target of a spell or ability an opponent controls, counter that spell or ability unless that player pays [cost].”

Some ward abilities include an X in their cost and state what X is equal to. This value is determined at the time the ability resolves, not locked in as the ability triggers.
