LP cost could be heavy depending on your remaining LP.
Steelswarm Genome counts as 2 tributes for Hercules’ summoning meaning you only need 1 more Steelswarm monster. You can tribute Steelswarm Caller to summon Steelswarm Mantis, Caller will special summon another Steelswarm monster from the deck while Mantis will special summon a Steelswarm monster from the graveyard. You now have 3 Steelswarm monsters that you can use as tribute to summon Hercules, use Double Summon if you want to summon him immediately.
Because Steelswarm Hercules uses so many tributes to summon, using Advance Zone and Trial and Tribulation during the turn he is summoned will allow you to use all 3 of both card’s effects.
You can use Monstermorph: Evolution to send Longhorn to the graveyard and summon Steelswarm Hercules from your deck, giving you a much more powerful monster that is able to wipe everything off of the field.
