When Cards Collide

Last Solution:

            My answer here isn’t really the best answer. As such, a reader supplies the answer here. Here is the answer from Minyu Zhou (18/7/5: Memorize the name. You'll be seeing it frequently). Not many people get into it this much, but this is very entertaining (18/7/5: though some of the ruling explanations on the judge list are spectacular. See Pole Position).

1. Flip one Magician of Faith to move Back to Square One from your graveyard to your hand.

2. Equip Gravity - Axe Grarl to Mataza. Its ATK rises to 1800.

3. Play Back to Square One. Toss out Sasuke Samurai from your hand, and return Jinzo to the top of your deck.

4. With Jinzo out of the way, flip Compulsory Evacuation Device to return Giant Orc to your opponent's hand.

5. Play Monster Gate. Sacrifice your face-up Magician of Faith to summon Jinzo.

6. Flip over the second Magician of Faith to move Monster Gate back to your hand.

7. Summon Berserk Gorilla in face up-ATK mode.

8. Play Creature Swap. Give your opponent Magician of Faith. Your opponent will give you his weakest (and only) monster, which is Homunculus the Alchemic Being.

9. Just for the hell of it, and just because you can, use its effect and declare Wind.

10. Play Monster Gate and sacrifice Homunculus as a cost.

11. Chain with Serial Spell and toss out your hand (which was only Sacred Crane and Monster Reincarnation). Serial Spell only duplicates the effect, not the cost, so for the price of one Homunculus, you get to summon the remaining two monsters (and cards) from your deck. Very good for teasing your opponent. You have to win this turn, and you WILL win this turn. Whew, good thing they don't have a Waboku or Kuriboh ready to foil your plans. You will summon Guardian Grarl (legal because the axe is already on the field) and Command Knight.

12. Now, from those two Gates, you have the following monsters on the field: Jinzo, Command Knight, Mataza the Zapper, Berserk Gorilla, and Guardian Grarl. In other words, your field is chock full of monsters. Your opponent only has your Magician of Faith in ATK mode on the field.

13. All your monsters are hungry to attack, so let's begin the fun part, shall we? Attack MoF with Command Knight. By its effect, its ATK is 1600, so your opponent loses 1300 LP (11,000 LP).

14. Attack your opponent's LP directly with Jinzo. Your opponent loses 2400 LP (8600 LP left).

15. Attack your opponent's LP directly with Mataza. Thanks to Command's effect and Gravity Axe, its ATK is now 2200. So your opponent's LP becomes 6400.

16. Mataza can attack twice, so do so. Your opponent loses another 2200 LP (4200 LP).

17. Now it's Guardian Grarl's turn to have fun. Have him attack your opponent directly, dealing 2500 damage (1700 LP left).

18. At long last, it's your Gorilla's turn. They call him Berserk Gorilla for a reason. P*ssed off as hell for having waited so long, he unleashes all his fury (and anger management issues) on your opponent, dealing another 2000 damage to win (-300 LP).

Final Result: You - 100; Him - (-300)



Problem – Win the Game in One Turn:

            This should be reasonably straightforward. Once you work out what you have to do, you see there is only one card that can do it. Unless of course there is a way of doing this I haven’t seen yet, which would be a shame because I didn’t really make this one that hard. If you see Berserk Gorilla and Gravekeeper’s, what do you think?


Field: (the upper part of the screen are your opponent’s cards)







Don Zaloog (face-up ATK)

Legendary Jujitsu Master (face-up DEF)

Enraged Battle Ox (face-up ATK)

Berserk Gorilla (face-up ATK)






Gravekeeper’s Spy (face-down DEF)




Witch of the Black Forest (face-down DEF)


Divine Wrath (face-down)

Monster Reincarnation (face-down)

Ultimate Offering (face-up)



Your Hand: 
Monster Reincarnation, Back to Square One, Double Spell, Zaborg the Thunder Monarch, Gravekeeper’s Assailant, Necrovalley, Gravekeeper’s Cannonholder



Your Life Points:                                 400  

Your Opponent’s Life Points:             5000


Your Deck Contains the Following Cards That You Can Obtain: 
Gravekeeper’s Curse, Gravekeeper’s Spear Soldier


Your Graveyard Contains:
          Gravekeeper’s Chief, Ghost Knight of Jackal


Your Opponent’s Graveyard Contains: 
Blessings of the Nile, Cost Down


If for any reason there is a choice that you have no control over, I expect ALL possible choices to work!  

Your opponent will activate Don Zaloog’s first effect when able if you have a card in your hand. Otherwise, he will activate the second effect.

You start during your Main Phase 1 having done nothing this turn.


Ten minutes ago, I found what was horribly wrong with #22. In my hurried rush to save the puzzle (Ghost Knight Special Summons to Defense Position damn it all) I found that there is not one card in Yu-Gi-Oh to simply change the battle position of one face-up monster on your side of the field. There are tons for everything else, but not that. I wonder why. Seems an obvious card. Must be a good reason…
18/7/5: Thanks to all of you that pointed out there are a few. Sadly, the only one I ever remember is Bite Shoes (no wonder I couldn't find one).

Also, today I have a guest contributor (for good this time). People send me puzzles and BOG-US cards all of the time, but recently the first very good BOG-US card contribution came through. Joe Mello presents Heart of the Cards. I hope you like it.
