When this card is Normal Summoned, you can select 1 monster your opponent controls. The selected monster cannot attack or be Tributed, while this card remains face-up on the field. During each of your End Phases, pay 500 Life Points or destroy this card.
You can Special Summon Lava Golem to your opponent’s field, and protect yourself for 1 turn. The next turn you can Normal Summon Grapple Blocker and lock down Lava Golem, so your opponent will still take 1000 Life Points damage every turn as long as Lava Golem is on their field.
These cards help you recover Life Points since you need to pay Life Points every one of your End Phase as maintenance cost for Grapple Blocker.
Remember to protect your Grapple Blocker if your opponent has multiple monsters on the field. You can only switch it to defense position during the next turn after you have Normal Summoned it.
This monster is completely negated by cards like Floodgate Trap Hole and Ultimate Providence, with Floodgate Trap Hole being very popular protection card in the current meta.
No Mortal Can Resist Can be used when your Life points are at least 1000 less than the opponent's. All monsters in the opponent's Graveyard changes to Skull Servants (Zombie / DARK / Level 1 / ATK: 300 / DEF: 200). This skill can only be used once per turn..
