Whenever one or more creatures you control that entered the battlefield this turn deal combat damage to a player, create a 5/5 red Dragon Spirit creature token with flying.
{1}{R}: Creatures you control gain haste until end of turn.
The set of creatures affected by the last ability is determined as that ability resolves. Creatures you begin to control later in the turn and permanents that become creatures later in the turn won’t gain haste. As long as Goro-Goro and Satoru is still on the battlefield under your control, it will gain haste.
