What does this card's "while this card is revealed from the deck, its name is also treated as [Omnimon]" mean, exactly?
This effect means that this card is also treated as a card with [Omnimon] while it's flipped over from the deck by a "reveal this card from the deck" effect. If the effect is an effect such as "add 1 [Omnimon] from the revealed cards," you can use that effect to add this card to the hand.
