Always keep the Twig.
The most important thing is to get the Twig early or mid game so that you can have it down to one charge when the rest of the components are in your hand. You can create four Malygos’ in one turn by playing the Fungal Lord, then Faceless Manipulator which creates three Lords, then break the Twig and play Malygos to generate four dragons, then play one or two Moonfires to face.
