Echoing Deeps I cant tell if the Caves deck is going to be good in Standard, but if so, this seems like a trap for that deck
As amazing as Lightning Bolt was, not everyone was convinced Creatures (11) Lands (20) Spells (29) The original eccentric deckbuilding success story, Erim Tams deck is best remembered for splashing Zurs Weirding, despite seeming like a Naya deck
That brings it down to $89.99 from $103.50 (as of this writing)
Look at delve cards like Treasure Cruise, undaunted cards like Curtains' Call, and random "mana-neutral" cards like Snuff Out and Frantic Search are great to cascade off
Otherwise, pulling just one card per turn leaves you about as threatening as a wet noodle
