An ideal way to play this card is with a "Gadget" Deck; having 3 copies of each "Gadget" monster in order to Summon all 3 "Egyptian Gods".

This also applies to "Crashbug", "Piece Golem", "Blackwing", "Frogs" and other decks that swarm.
"The Winged Dragon of Ra" cannot be Special Summoned, but two Divine-Beasts can be. Tribute Summon "The Winged Dragon of Ra" (with any strategy above) and Special Summon the others with cards like "Monster Reborn" or "Call of the Haunted" to Summon Horakhty.
Since "Gadgets" are Level 4, you can use "Lavalval Chain" and "Daigusto Emeral". "Lavalval Chain" can put an "Egyptian God" card or "Horakhty" on top of your Deck, and "Daigusto Emeral" can retrieve used "Gadgets".

You can Special Summon this card easily if you banish "Obelisk the Tormentor" and "Slifer the Sky Dragon" (with cards like "Gold Sarcophagus") while you control "The Winged Dragon of Ra". Simply use "Return from the Different Dimension" to Summon "Slifer" and "Obelisk", and then Tribute all 3 for an Instant Win.

If "The Winged Dragon of Ra" is in your hand, you can use the above strategy by banishing 3 other monsters along with "Slifer" and "Obelisk". Just Tribute the 3 other monsters for "Ra"

If you play a "Skull Servant" or "Ojama" Deck, you can use multiple copies of "Tri-Wight" and an "Ultimate Offering" to Tribute Summon all the "Gods", then Tribute them for this card.
