This card's swarming effect is geared specifically for Yusei's deck, which has many Level 2 or lower Machines and Warriors.
In episode 45, Yusei Fudo uses this card during his Ground Duel against Roman Goodwin. He Synchro Summons this card by tuning "Quillbolt Hedgehog" and "Tuningware" (which was treated as a Level 2 monster via its own effect) with "Road Synchron". Yusei then draws a card as per the second effect of "Tuningware". This card then attacks "Underground Arachnid", but Roman destroys the "Shield Wing" equipped to "Underground Arachnid" to prevent its destruction, however he still takes Battle Damage. At the end of the Damage Step, the first effect of "Spider Web" activates, switching this card into Defense Position. Roman states to Yusei that he intends to use the second effect of "Underground Arachnid" to equip itself with this card during his next turn in order to allow "Underground Arachnid" to attack directly. Yusei then activates this card's effect to Special Summon "Turbo Booster" from his Deck. He then activates the effect of "Turbo Booster" to Tribute itself and destroy "Underground Arachnid". In the next episode, Yusei activates this card's effect to Special Summon "Speed Warrior". Roman then activates the effect of "Ground Spider" to switch "Speed Warrior" to Defense Position. Yusei then activates "Advance Draw" to Tribute this card and draw two cards.
