This card can be very useful in a RFG deck to allow you to re-use "Macro Cosmos" if it's destroyed.
This card could be well used in a deck using "Uria, Lord of Searing Flames". Use it to bring back a trap used to summon him if you have enough continuous traps already in the graveyard to boost his ATK.
In a "Paleozoic" deck, you can chain this card to the activation of your Trap Card for later re-use, then Special Summon a "Paleozoic" Trap Card from your Graveyard as a monster in response to the activation of this card. You can use the discard cost of this card to your advantage by discarding another "Paleozoic" Trap Card to Special Summon later.
