pokemon black white card list SV: Bolt | Buyer's Guide to Pokémon TCG

Delve is an ability that allows you to exile a card from your graveyard to reduce the cost of the spell by one mana

I recommend: Sol Ring, Mana Crypt, Mana Vault, Grim Monolith, Ruby Medallion, and that new card Jeweled Lotus

Its also a strong card to include if you plan to mill your opponents or benefit from their graveyard

Not quite as amazing as this card, but may be worth looking into

Players enjoyed the opportunity to get multiple rares, having a guaranteed foil slot, having an opportunity to open a card from The List , getting an art card, etc

This ability doubles your army with each activation, allowing you to go from a handful of Goblins to hundreds in a single turn
