Keep in mind, this card can still be used as a Level 4 monster. This allows combos with "Goblindbergh", and similar monsters into a Rank 4 Xyz Summon with a draw to replenish your hand.
This card combos well with "Instant Fusion" to summon Level 4 or 5 Fusion Monsters, giving you flexibility to Summon a Rank 4 or Rank 5 Xyz Monster.
If playing a "Spellbook" deck, you can easily gain card advantage with 1 or 2 copies of this card. It can also be revived with "Monster Reborn" or "Spellbook of Life" (Also if using the latter card, this card still can be treated as a Level 5).
