"Cannot be Normal Summoned. Must first be Special Summoned (from your hand) by banishing 3 Dragon-Type Normal Monsters from your Graveyard." is not treated as an effect. It is a procedure to Special Summon a Special Summon Monster. (Banishing 3 Dragon-Type Normal Monsters from your Graveyard is a procedure for the Special Summon. A Chain Link is not built when performing a Special Summon this way.)
If this card was successfully Special Summoned from the hand by the method written in its text and was subsequently sent to the Graveyard, it can be Special Summoned from the Graveyard by the effect of "Monster Reborn".
"Once per turn: You can banish 1 Dragon-Type monster from your Graveyard; target 1 card on the field; destroy it." is an Ignition Effect. (When activating this effect, banishing 1 Dragon-Type monster from your Graveyard is a cost.)
