Celebration — As long as two or more nonland permanents entered the battlefield under your control this turn, Goddric, Cloaked Reveler is a Dragon with base power and toughness 4/4, flying, and “: Dragons you control get +1/+0 until end of turn.” (It loses all other creature types.)
Celebration abilities only care if two or more nonland permanents entered the battlefield under your control in a turn. They won't get more powerful if more than two permanents entered the battlefield under your control in a turn.

Some celebration abilities trigger at specific parts of the turn and check whether two or more nonland permanents entered the battlefield under your control already in that turn.

The permanents that entered the battlefield don't need to remain on the battlefield or under your control. Celebration abilities are checking for past events, not the current game state.

Goddric's activated ability affects only Dragons you control at the time it resolves. Any Dragons that come under your control later in the turn won't be affected.

If an effect causes Goddric to lose all abilities during a turn in which it has already become a Dragon, he's still a Dragon creature with base power and toughness 4/4.

Others are static abilities that give creatures abilities or power and toughness increases as long as two or more nonland permanents entered the battlefield under your control that turn.
