The nice thing about this set compared to Obsidian Flames is, that this does have 3 Japanese sets mixed in, with Obsidian Flames this was only 1 set
Honestly this might be even better than the Tracker: while I love Clue Tribal and card draw, cracking clues for 2 mana a pop adds up real fast, and often times I don't crack any Clues until mid/late game
Thats what makes it extra crazy that the early days of Magic had tournament-legal cards that did exactly this kind of thing
Draw cards and pressure with Crystal Waltz
Each card is designed in a fun trading card style, making it ideal for print, cut, and play activities
It's not a game-winning spell, but it's good
