Meliae of The Trees

Meliae of The Trees (credit)

This is just what plant decks needed. All you need two level three earth monsters for her. That could be Dandylion and any other level three Earth monster.  Her first effect allows you to send a plant monster from your deck to the graveyard. Then if she survives until your next turn you can special summon a plant from your graveyard. This can be useful for sending a Dandylion to the graveyard.

Try this combo: summon Rescue Rabbit, and then use his effect to special summon two Jerry Beans Mans and, finally XYZ summon Meliae of The Trees. Later you can use the Jerry Beans Mans and Masked Chameleon to synchro summon Black Rose Dragon!
