if you have no cards in hand mtg Phial of Galadriel (LTR) #699 One With the Void (legendary)

this deck will slowly get better as more cards are printed (and bad ones rotate out of the deck)

It's a key piece of a ton of Legacy decks where it features in combos from Storm to Dredge to Goblin Charbelcher

Grixis provides some powerful options at the cost of a weaker manabase, which means you cant play four Counterspell and four Archmages Charm without taking a ton of damage

Each includes 1 deck of 100 Magic cards (98 nonfoil cards and 2 Traditional Foil Legendary cards), a 2-card Collector Booster Sample Pack (contains 2 alt-border cards of rarity Rare or higher, at least 1 of which is Traditional Foil), double-sided token cards (6 in Counter Blitz, 10 in the others), 1 deck box (can hold 100 sleeved cards), 1 strategy insert, and 1 reference card

It's in the conversation for best colorless removal spell of all time, which is notable, although just how much that matters is up for debate
