Gameplay in CCG is typically turn-based, with each player starting with a shuffled deck, then drawing and playing cards in turn to achieve a win condition before their opponent, often by scoring points or reducing their opponent's hit points
With a wide pool of cards, it helped players to collect all the cards they were missing
Monsters Cost are equal to the sum of ATK and DEF, divided by 100 (rounded down if the sum ends in 50 rather than 00)
So running too much mill is extremely counterproductive, as it vastly shortens the deck's staying power in exchange for a bit more explosiveness
While mods are the most efficient way to open up packs quickly, there are also a few things that players can do without the use of mods that speed things up
With 3 Strength, 5 Willpower and even 2 Lore, Aurora, Dreaming Guardian is an excellent, well balanced card that provides excellent support to your other characters too
