Stall

Stall cards are cards that are used to prevent your opponent from attacking you.

Common Stall cards include:

Monsters - Spirit Reaper, Big Shield Gardna and Battle Footballer

Spell - Level Limit - Area B, Swords of Revealing Light and Nightmare's Steelcage

Trap - Gravity Bind and the DNA Surgery / Insect Barrier combo

Decks usually include stall cards as part of a larger strategy such as a Burn deck or an Exodia deck. They are also used to buy time for a player if their opponent gains an advantage over them.
