Examples are countless: a suspended Rift Bolt from turn 3, a sac-damage creature (like Bile Urchin, Death Cultist, Emberwilde Augur, Seal of Fire) , a "T:deals 1 damage to target (creature or) player"-creature (Goblin Fireslinger, Prodigal Pyromancer, Cunning Sparkmage, Cinder Pyromancer, Rakdos Ickspitter) or a similar aura to cast on a creature you already had since turn 2 (Fire Whip, Lightning Prowess and so on) The other route is "not casting it": Fleshwrither's unique put-into-play-from-library ability that works because both rakdos and this horrific guy cost 4 mana total (not doable on turn 4) using things that let you put it into play from your hand like Through the Breach or Quicksilver Amulet putting Rakdos into the graveyard and reanimating it directly into play
