Fun Penguin Deck I'm trying to rework

My original strategy was to just get Penguin Brave out as fast as possible but now I'm trying to rework this deck to allow other Synchro Monsters. Sometimes I am able to build 7-9 level Synchros but I don't have them in the Extra Deck. I think this way allows me to play different level Extra Deck Monsters, depending on which of the many Penguins are on my field.

I now have 9 Tuners which gives me more versatility.

I haven't played this variation of the deck yet, so this is more of a placeholder of the cards I would like to throw into it. Let me know if you have any tips on what you would do with these potential cards in a deck?
