- You can use "Card Guard" to protect monsters that can't be destroyed in battle, such as "Blackwing Armor Master".
- You can place the "Guard Counter" on another "Card Guard" to have its ATK become 2200. Or swap guard counters between 2 card guards to have their ATK maintained at 1900 but with the added protective effect of the counter.
- This card is useful in conjunction with "Burden of the Mighty". You can play "Burden of the Mighty", put "Card Guard's", "Guard Counter" on "Burden of the Mighty" to prevent it from being destroyed once. "Card Guard" will drop to 1600 attack, but even level 4 1900 attack monsters wouldn't be able to destroy "Card Guard" at that point.
- You can Special Summon this card from your Graveyard with the effect of "The Dark Creator", and place all "Guard Counters" on "The Dark Creator" to create a hard to destroy monster.
- Return a "spent", "Card Guard" to your hand with "Compulsory Evacuation Device" or "Mist Valley Falcon" to use its protection again later.
- This card is powerful alongside "Doom Shaman"; its "Guard Counters" make "Doom Shaman" more stable, and it can be revived for layered protection.
- You can use it to protect "Toon World" or any field spell to protect your "Earthbound Immortals" and your "Malefic" monsters.
- This card can help you protect your "Armed Dragon LV3" for the summon of "Armed Dragon LV5" .
- Protect Spell Chronicle with the counter to ensure its longevity and increase the odds that it survives for long enough to let you you end up with your chosen cards.
- Use this card's effect on Call of the Haunted, Fiendish Chain, Safe Zone or any other Continuous Trap Card that Destroys itself when its target monster is removed/destroyed. Once that happens, the card will simply lose its guard counter instead of going to the Graveyard, leaving it behind as ammunition for cards such as Scrap Dragon, Trident Dragon, Storm and Scrubbed Raid.
- You can also bounce the card with Gravelstorm to reuse it or trade it for Life Points with Emergency Provisions.
