In many decks, this ends up costing very little mana indeed
When you do find a deck, you can at least help fill it out by crafting missing cards using the resource of CP, which is obtained by dismantling cards you dont want or need - a welcome change from hoping you pull the right card from a booster
Based on how theyve designed sets for the last half decade, youd think theyd be ecstatic if basically every deck in Standard looked like this: Creatures (15) 2 Torrential Gearhulk 4 Glint-Sleeve Siphoner 2 The Scarab God 4 Goblin Chainwhirler 3 Nicol Bolas, the Ravager Planeswalkers (3) Lands (26) Spells (16) 2 Magma Spray 2 Essence Scatter 3 Harnessed Lightning 1 Glimmer of Genius 1 Commit 1 Abrade 1 Supreme Will 4 Vraska's Contempt 1 Search for Azcanta Sideboard A dozen of the formats best mythic rares, a dozen of the formats best removal spells, rinse and repeat

However, some of these cards are an integral part of the game's retro history, as many of them are reliable control cards that shape the meta of the game's retro formats
