When this card is destroyed by battle and sent to the Graveyard, you can add 1 Level 3 or lower Beast-Type monster from your deck to your hand.Now, why would this card be interesting, you ask? Simple. Moja decks have a field day with this! It's compatible with Kinka-Byo, One-for-One, searchable by Giant Rat, Super-Nimble Mega Hamser and Sangan, and searches for Moja, Airbellum, and Kinka-Byo.
So why would it be worth it besides just that? Some of you may simply wonder if it's worth the hassle, but this little mouse has another trick...it's a Tuner!
By making it a level 1 Tuner, it allows Moja decks to have constant access to lvl 8 Synchro Monsters, every 2 turns if possible.
For those of you who play Moja decks, you know that Moja gives access to King of the Beasts (KOTB) as it's main attacker most of the times. Kinka-Byo allows for Moja and KOTB to be constantly be returning to the field. But what do you normally do when you already have KOTB on the field? Kinka-Byo just sits in the hand waiting for it to return.
However, what if Kinka-Byo could also aid KOTB by bringing out a new friend? By using it's effect when KOTB is still out, bring back Keymouse and synchro for lvl 8, or a lvl 9 (Trishula and Mist Wurm) depending on your situation. Due to Kinka-Byo's effect to return to the hand, Keymouse and KOTB could become quite the troublesome duo.
Give it a try, you might like it!
