"Genex Blastfan" can be particularly useful with this card, as its searching effect triggers when Special Summoned by "Accelerator's" effect, meaning you add them to your hand and then Special Summon another monster.
This card's effect will trigger even by drawing "Genex" cards.
This way, cards that allow you to draw many cards in one turn can be very powerful coupled with this. For example, "Reckless Greed", "Hand Destruction" and "Maxx "C"" all can lend into a extremely fast swarm that can either result into an One Turn Kill or Summoning monsters to protect yourself from one.
Use with "Genex Undine" to get a free Level 6, 7, or 10 Synchro Monster.
