If this card is Normal or Special Summoned: You can Special Summon 1 "Destiny HERO" monster from your hand with ATK less than or equal to this card's. You can only use this effect of "Destiny HERO - Drilldark" once per turn. If this card attacks a Defense Position monster, inflict piercing battle damage to your opponent.

Since it's attack can be pretty low in comparison to many commonly used level 4 monsters, you can increase its attack by using skills that give you the field spells, or bringing them in the deck. Joey's exclusive skill "Fields of the Warriors" gives you Sogen at the start of the duel, and Aster's skill "Destiny Calling" is for Dark City when your LP is at 3000 or lower.
Many of the level 4 or lower monsters have about 1600 or less attack, making them able to be special summoned if you also have these in your hand. They can be good in certain situations, but it's mostly good if paired up with The A. Forces to bump up your attack.
A good option to special summon using Drilldark's effect is to special summon Celestial. It has an effect that can destroy your opponent's face-up spell card when it declares an attack, but it also has an effect that lets you draw 2 cards when you have no cards in hand. This makes it so that even if it gets destroyed, it sets you up for your later turns, or get some of your resources back when you fusion summon Destiny HERO - Dangerous.
