When a Machine-Type monster you control is destroyed by battle and sent to the Graveyard while this card is face-up on the field, you can add 1 Machine-Type monster with 1000 or less ATK from your Deck to your hand.

How to get / Rarity

Level-up reward--

Card trader--




  • Slightly above average attack.
  • Can search for some Machine type monsters from your deck.


  • The effect only works if you control this card face up and your opponent destroys another machine type monster you control by battle.
  • Limited options as to what it can search.



It can work well with union monsters since Heavy Mech Support Armor lets you special summon a monster from your graveyard. Otherwise, it can provide some support for other deck types that uses low level machine monsters.

Search or destroy

Since it only works when your opponent destroys another machine type monster you control while Biofalcon is on the field, your opponent will most likely want to destroy it first instead of trying to attack your other monster(s). You can either use Staunch defender to shift the focus, or use defensive cards to protect itself.

Instead of this thing, Crowler event should have given us Ancient Gear Wyvern or Ancient Gear Howitzer.

Either of those two would be so much more useful for AG decks than this thing.

I actually complained about Biofalcon being a reward because of how useless it is in an AG deck.....

No sane person runs AG Cannon and Ancient Gear (the stupid weak Level 2 monster)
The function for this card added in this event was to "supposed" using to search ancient gear box to active it's effect and search another ancienter gear card.

Must have two monsters on the field and your opponent must choose to let you use its effect by attacking the other monster.

Puts box in your hand, not on field.
Box lets you summon Knight.
That's a lot of steps and ifs for an 1800/500 beater that needs to be gemini summoned to get its effect.

Alternatively: Biofalcon > gear Cannon.
Woop de doo, 500 lp damage. Hope that was worth it.

Yeah, Biofalcon is useless not to mention not being an AG card, and AG deck actually runs just fine without Box.

Yet they put Biofalcon so high up in the reward list....
