OK. Time to explain rulings.

First off, the card everyone is currently discussing: Ancient Gear Castle. Master of Paradox mentioned one mistake he made, but he actually made a second. The exact text of the card states that you add a counter "each time a monster(s) is Normal Summoned or Set," meaning Chad's comment about Setting monsters was incorrect. However, it is very true that the Castle gains counters when your opponent Normal Summons or Sets as well, since it does not specify which side of the field the monster must be Normal Summoned or Set on.

Second, Ancient Gear Cannon. Its effect is considered an 'Ignition Effect'. This is important because that means it is not a 'Multi-Trigerr Effect', which is the only kind of effect that can be activated during your opponent's turn. So, you can Tribute Ancient Gear Cannon during your own turn.

Third, even if you were allowed to Tribute the Cannon during your opponent's turn, that would've invoked a generic game ruling: if the number of monsters on your opponent's side of the field changes during an attack, you may rewind the attack and select a new target if you choose. Tributing Cannon would have changed the number of monsters on Sol's field, thus allowing Chad to call back his attack (technically called a replay) and attack another target (such as Sol).

Fourth: I can't remember in which battle, and I'm too lazy to look it up, but I remember Chad activating his Wild Nature's Release sometime during a Battle Phase. Wild Nature's Release is a Normal Spell, with a Spell Speed of 1; only cards with a Spell Speed of 2 or higher (such as Quick-Play Spells) can be activated during the Battle Phase.

Now that those are out of the way...I certainly do appreciate seeing Kyle's Deck extending past TTYD (I was the one who created him, jkB). And, since it's obvious that Sol will appear at least one more time, we'll be able to see a few more strategies in that Ancient deck of his.

until next chapter, then, this is StarJake, signing off.
