1x LP copy of Seismic Assault, from 8th Edition. This Rare Red Enchantment is a key card and namesake of Modern 'Seismic Swans' U/R decks, which use Seismic Assault to damage Swans of Bryn Argoll for card advantage, eventually accruing enough lands to send lethal burn at your opponent. 

This card is also a great inclusion in the recently released Commander 2018 Lands-Matter Jund deck.
