You can even use this card politically to enable an opponent to get through for damage on a player thats starting to become a threat to the rest of the table
You won't return the target card to the battlefield
Now, as to this actual card: the Scarlet Spider is such a good aggro option
The Golgari deck from Worlds Top 8 had four Cottages and three Tortoises, with the Tortoise able to find a Cottage (or bring one back from the dead), while also reducing the cost of activating it (allowing the potential for multiple creature lands to attack each turn), and even pumping them
If these were legal in the format, combo decks would likely dominate the format, just as they did at Pro Tour Philadelphia
It turns cards like From Under the Floorboards into Plague Wind, which isnt an exaggeration
