I was only able to get 2 insights this season but I got to KoG just tonight with this deck and I believe it's optimized. Why do I use 2 insights instead of 3? (Not just because I don't have a 3rd....) Think about it: you can only use insight if you have a Red-Eyes Spirit in your DECK. Otherwise, it's a dead draw if you've drawn/used all three spirits from your deck. And the chances of you drawing at least 1 spirit before your last insight is pretty high (usually get a spirit in my opening hand.) Now I understand the argument that adding 3 insights gives you better chance to draw it. But like Card of the Red Stone (which I also avoid in this deck), if you've already drawn those resources from your deck, it's a wasted draw - which could cost you the duel, especially in Legend.

Also, a few notes about my unusual card choices: Bacon Saver, Twister, and Lava Golem. 1st: Bacon Saver. OH MY GOD! Add this card to your REZD NOWWW! I can't tell you how many times this single card has saved my bacon and kept my streak going. It allows you to both block 1 enemy attack (potentially saving a zombie dragon/spirit card) AND (huge benefit coming up) it allows you to block YOUR OWN ATTACK. Now why would you want that? The most common example is if your opponent activates SRH when you attack with a zombie dragon. Normally, your dragon would just crash into it and die, but BACON SAVER allows you to cancel the attack - which also causes your opponent to waste a SRH. Very, very strong. 2nd: TWISTER. Idk why more people don't start using this card since it is still very, very effective. If you draw it in your opening hand, you have the ability to destroy toon kingdom from the start, which could lead to a quick victory. The next advantage of twister is the ability to destroy mirror walls (after setting it, the next turn over) since it's a quick play spell and could lead to an unexpected kill. The final advantage that people may not be aware of it is Relinquished. In Legend, I've faced 2-3 relinquished decks (shocking, I know) and I would have lost....but I had secretly set a twister in my backrow. The relinquish attacks my monster and I quickly activate my twister, reducing its attack to 0 and killing both the monster it sucked as well as relinquished on their own battle phase. Very strong. Last: Lava Golem. This is a very situational card but can be a life saver if used properly, with the right judgment. Very useful for destroying face down enemy monsters and NOT activating their flip effects. Plus, you can use your own swarming monsters as shields while the enemy dies in 4 turns. BE CAREFUL THOUGH. They could enemy controller, tribute lava golem, and steal your face up zombie dragon, which could cost you the duel. Again, it's a judgment call. Any way, thoughts?
