One of the most popular cards to include in an infect deck, especially ones featuring green, is Vorinclex, Monstrous Raider because it doubles the number of any type of counters placed on a permanent or a player
Whenever you sacrifice a Clue, you may have Lazav become a copy of a creature card exiled with it until end of turn
There's still more though, as Goldspan Dragon also makes it so that you can sacrifice your treasure tokens for two mana instead of one
All told this is not the ideal way to try and fill up your yard despite having some utility there, What it is good for is being an alternative Welder / Tinker target with very high power
Considering your goblin does have power 2 or less, it should be all but dead
If multiple cards are put into the library this way (such as when this spell targets a melded permanent), that permanent's owner puts all the cards second from the top or all the cards on the bottom
