bloomburrow collector booster box case - Play the bucolic and vibrant home to the animalfolk of Bloomburrow Bloomburrow Collector Box Opening x4:

Pairing this with the Level 5 Infinitrack Monsters can come in handy to Xyz Summon Infinitrack Riverstormer , or if you choose a Level 10 monster, it allows you to access the powerful Rank 10 Superdreadnaught Rail Cannon Gustav Max to inflict 2000 damage to the opponent

The 3 effect is Diamond Guy's support effect, and while it's nice to be able to put a Normal Spell that normally doesn't work on his Deck on the top of his Deck, the opponent will also receive the same effect, so you'll need to use it systematically

This should give you even more opportunities to get rid of junk low value cards, or just sell custom boxes for fun

This one is also EARTH Attribute just like the other level 3 option, however this one comes with a wide array of abilities, including making another monster you control a Tuner monster
