Card Tips:Ground Collapse
- This card can be searched by "Rogue of Endymion", "Watch Cat", "Watch Dog", "The Despair Uranus", and other generic searchers.
- With two "Ground Collapse" face-up on your field, most of your opponent's Monster Zones will be blocked.
- If this card and "Ojama King" are on your field, your opponent can't Summon any monsters except to the Extra Monster Zones. Alternatively, you can also combine with "Ojama Trio", although this is not recommended if your opponent is using Link Monsters.
- You can use this card to lock out your opponent's linked Main Monster Zones, so they cannot Summon more monsters from their Extra Deck.
- Use three copies of "Ground Collapse", "Secret Village of the Spellcasters", "Royal Decree" and any Spellcaster-Type monster for a complete lockdown.
- If the last two cards are lacked, "Xing Zhen Hu" could be used instead.
- Alternatively, "Naturia Bamboo Shoot" that was Summoned with its effect can be used to still give you access to Spells and Traps while completely locking your opponent's field.
