Guardian Grarl
Card effect (current official text)Cannot be Summoned unless you control a face-up "Gravity Axe - Grarl". If this is the only card in your hand, you can Special Summon it (from your hand).
Rulings
- If you wish to use Guardian Grarl's effect to Special Summon him from your hand, you still must have Gravity Axe - Grarl on your side of the field.
- You cannot Tribute Summon Guardian Grarl by Tributing a monster equipped with your only Gravity Axe - Grarl on your side of the field, because the Gravity Axe - Grarl will no longer be on the field when the Summon occurs.
