Thats a lot more broad of a category than mana value 2 or less, and if you build your deck right, this just draws you a card every time you activate it
UR Ultra Rare Stealth Bird X DARK Level 3 [ Winged BeastEffect ] ATK 700 DEF 1700 Once per turn: You can change this card to face-down Defense Position
Tokens can be used to reduce the cost thanks to the spell's convoke keyword, meaning if you're going wide it can be played for as little as three white mana
Because these are the cards that have been used up, the discard pile is public knowledge to both you and your opponent and is face up the entire game
So instead of constantly having to manually set values for card name, HP, attacks and Pokmon Powers, etc, you can predefine those values, ensuring they are always a click away
