"Junk Synchron" and "Dark Bug" are capable of Summoning each other and together meet this card's Summoning requirement. Three copies of each and "Dark Eruption" give the controller plenty of chances to Summon this card at the expense of only one card from their hand.
In a Junk Deck, you can use this card to get around "Evilswarm Ophion" by reducing his attack to 2000 and be destroyed. This will allow you to synchro summon as usual since Ophion severly cripples Junk Decks.
The Dark Synchro version of this card can be exploited by equipping a card to the opponent's monster to boost their ATK, then attacking the monster. This can mill the opponent's Deck in one move if the opponent's monster has high enough ATK in comparison to this card.
